Blog Refreshed Part Two

2011-01-20T07:01:00Z

This a shorter post, and maybe more of just a Mango Blog plugin post.

So in part one I went of the tweaks that I made to help me for entering and editing blog posts. Now I will show you what I did to fixed the code formatting. Again I created a plugin, the plugin that I created using coldFish(coldfish.riaforge.org) to format the code in my blog entries. Here is my plugin xml.

This plugin listening for the "postGetContent" event.

Now time for the handler code. In the init function we are setting "variables.coldfish" equal to the coldFish component.

In the processEvent function I am using some code from BlogCFC from the blog component renderEntry function, thanks Ray. The only thing that I really want to point out in the function below is how I am overriding the content variable which is where the blog post is stored "arguments.event.accessObject.content". Also in the code below added spaces within the < code > tags for this post only.

Blog Refreshed Part One

2011-01-19T07:01:00Z

Well I have refreshed the theme on my blog. I wanted to switch to blogCFC because the tinyMCE was messing up my posts when I had code in a post. So I attempted to install blogCFC on the server where my site is hosted and I just could not get it to work. The problem that I had was with the SQL server scripts. I am on an older version on SQL server and it looks like the scripts were exported/written for SQL Server 2008, I did not want to change the scripts because if there was an update later for blogCFC, most likely I would not remember that I modified the SQL script. So I decided that I would figure out how to make Mango Blog work better for me starting with the tinyMCE and then on to the actual formatting of the rendered code.

So how did I do this? Well in Mango Blog they have this really cool feature called plugins that listen for events. I decided I would write a simple plugin that removes the tinyMCE if the event sees a URL variable called “noEditor” and the events that I am listening on are ( "beforeAdminPostContentEnd", "beforeAdminHeaderEnd" ). The first thing that you need to do is create a plugin.xml file, here is what mine looks like.

The next step is to create a handler.cfc file this is where you add you CFML. I am not going to go into what all the functions do because you can find the Mango Blog documentation http://www.mangoblog.org/docs/documentation/extending-mango/creating-a-plugin. The function that I am using is the function that is for "Synchronous event handling" processEvent. Here is my function.

52                                        $(this).parent().append( new_button );

65
66        </cfif>
67
68        <cfreturn arguments.event />
69    </cffunction>

Ok lets break down the code above. The first thing that I am doing is setting my variables.

view plain print about

1<cfset var eventName     = arguments.event.getName() />
2    <cfset var externaldata = arguments.event.getrequestData().externaldata />
3    <cfset var _scriptHead     = "" />

The first variable ("eventName") is the name of the event being executed, the second variable ("externaldata") is for all of the external data like form and url variables, and the last variable will be used for storing the output for the html head.

Next is my if statement which really only needs to be in there if you're listening for multiple events, in this case I am listening for two events ( "beforeAdminPostContentEnd", "beforeAdminHeaderEnd" ).

view plain print about

1<cfsavecontent variable="_scriptHead">
2    <cfoutput>
3    <cfif isStruct( externaldata ) and structKeyExists( externaldata, 'noEditor')>
4    <script type="text/javascript" language="JavaScript">
5        $(function()
6        {
7            $("textarea##contentField").removeClass('htmlEditor');
8        });
9    </script>
10    </cfif>
11    <style type="text/css">
12        .widget{
13            width:75%;
14        }
15        ##contentField{
16            width:80%;
17        }
18    </style>
19    </cfoutput>
20</cfsavecontent>
21<cfhtmlhead text="#_scriptHead#">

In the code above I am listening for the event "beforeAdminPostContentEnd" and then I overide the admin css and I added so jQuery to remove the "htmlEditor" class form the textarea with the id "contentField", if I find the struct key "noEditor". The next part I am taking the script and style output and putting it in the html head.

1<cfif isStruct( externaldata ) AND structKeyExists( externaldata, 'raw') AND isArray( externaldata.raw ) >
2    <cfset arr_index = (externaldata.raw.indexOf('posts.cfm')) + 1 />
3
4    <cfif val( arr_index )>
5        <cfsavecontent variable="_scriptHead">
6            <cfoutput>
7
8            <script type="text/javascript" language="JavaScript">
9                $(function()
10                {
11
12                    $('tr td.buttonColumn a.editButton').each(function(index) {
13                     if( $(this).text().toLowerCase() == 'edit')
14                        {
15                            var new_button = $(this).clone();
16                            new_button.attr('href', new_button.attr('href') + '&noEditor=true' ).text('Edit No Editor');
17                            $(this).parent().append( new_button );
18                        }
19
20                     });
21                     $('p.buttonBar a.editButton').each(function(index) {
22                            if( $(this).text().toLowerCase() == 'create new post')
23                            {
24                                var new_button = $(this).clone();
25                                new_button.attr('href', new_button.attr('href') + '&noEditor=true' ).text('Create New Post No Editor');
26                                $(this).parent().append( new_button );
27                            }
28                        });
29                });
30            </script>
31
32            </cfoutput>
33        </cfsavecontent>
34        <cfhtmlhead text="#_scriptHead#">
35    </cfif>
36
37</cfif>

Next in the elseif statement I am listening for the event "beforeAdminHeaderEnd". Here we're going to look through the attribute raw element which is an array and stores the name of the file name, the file name that we're looking for is posts.cfm. Once I find the file name I add some more jQuery that will look through the DOM for "tr td.buttonColumn a.editButton" and "p.buttonBar a.editButton" then I add two new buttons, one that will allow me to edit a post without the editor and one that will allow me to create a new post without an editor.

The only problem that I have found with all of this, is that once I save my blog post the page redirects back to the post.cfm file but no "noEditor" url var so I still need to work on that. If you want the plugin here is the download link.

Internet ID for all?

2011-01-10T08:01:43Z

Obama administration moves forward with unique internet ID for all Americans, Commerce Department to head system up

President Obama has signaled that he will give the United States Commerce Department the authority over a proposed national cybersecurity measure that would involve giving each American a unique online identity. Other candidates mentioned previously to head up the new system have included the NSA and the Department of Homeland Security, but the announcement that the Commerce Department will take the job should please groups that have raised concerns over security agencies doing double duty in police and intelligence work. So anyway, what about this unique ID we'll all be getting? Well, though details are still pretty scant, U.S. Commerce Secretary Gary Locke, speaking at an event at the Stanford Institute, stressed that the new system would not be akin to a national ID card, or a government controlled system, but that it would enhance security and reduce the need for people to memorize dozens of passwords online. Sorry, Locke, sounds like a national ID system to us. Anyway, the Obama administration is currently drafting what it's dubbed the National Strategy for Trusted Identities in Cyberspace, which is expected at the Department of Commerce in a few months. We'll keep you posted if anything terrifying or cool happens.

So what does this mean? Are we going to have one Internet ID and password that is stored with the Government? Would you trust the Government with your ID and password? We all know that they spy on us already

jQuery jNotify

2011-01-09T10:01:00Z

jNotify is a jQuery plugin to send notifications to your users with a single line code.

jNotify can display information boxes in just one line of code. Three kind of boxes are allowed : information, success and failure. The whole box is entirely skinnable with css. For example, you could use it for a mail being successfully sent or a validation error of a form.

This a great easy to use plugin to notify your users about events within your app. For instance, I used this plugin to my users know if an AJAX request had an error or if it was successful.

Here is an example of creating an error and success message.

1$(function()
2            {

4                $('#show_error').click(

6                    jError('I am sorry, something did not go right!',{HorizontalPosition : 'right', VerticalPosition : 'top'});

14                }
15                );
16            }
17        );

Demo

As you can see it is quite simple to use.

Well I finished day one and two of IO and so far I am not too fond of the language. Finding any information on this language is quite hard. Actually most of the information that I have found has been from www.bennadel.com. I am not going to post my homework for this language for this day since most of my information has been from Ben's site.

Fresh Invoices

2011-01-05T06:01:44Z

I have been using FreshBooks for over a year now, and it’s definitely the best online solution that I have found. Some of the issues that FreshBooks has solved for me are tracking expenses, like mileage office supplies and you can also setup recurring expenses. In the free version can setup three clients and send unlimited invoices via email they will send your invoices via snail mail but you will have to by FreshBook stamps. You can send your client an estimate and then turn that estimate into an invoice. If you are interested click the banner below.

Seven Languages in Seven Weeks: Ruby Day 3

2011-01-05T08:01:00Z

The third and final day of Ruby. This was full of fun, we learned about the power of "missing_method", and how to use it to create your own (DSL). We also learn how create and use modules, modules are pretty cool I liked how you can create a module and mix it in a class. Now on to the homework, todays homework was quite a challenge but also fun.

Moving back to BlogCFC

2011-01-05T07:01:07Z

After painfully trying to use Mangoblog I have decided that I am going back to blogCFC.

My First attempted at the "The Adapter Pattern/Wrapper Pattern"

2011-01-03T08:01:00Z

A friend of mine turned me on to a new pattern that I think I will be using more in the future "The Adapter Pattern/Wrapper Pattern".

Intent

Convert the interface of a class into another interface clients expect. Adapter lets classes work together that couldn’t otherwise because of incompatible interfaces.
Wrap an existing class with a new interface.
Impedance match an old component to a new system

--Source http://sourcemaking.com/design_patterns/adapter

So to play around with this concept, I had just shared with him payment gateway service. The function I was working on was a function called getGateway(), and it looked like this

view plain print about

1<cfargument name="MerchantProps" required="true" type="struct" >
2        <cfscript>
3            var gw = {};

6            {
7                case 'itransact':
8                {
9                    gw.path             = "itransact.itransact_cc";
10                    gw.MerchantAccount     = arguments.MerchantProps.MerchantAccount;
11                    gw.Username         = arguments.MerchantProps.Username;
12                    gw.Password         = arguments.MerchantProps.Password;
13                    break;
14                }
15
16                case 'authorize':
17                {
18                    gw.path             = "authorizenet.authorizenet";
19                    gw.MerchantAccount     = trim( arguments.MerchantProps.MerchantAccount );
20                    gw.Username         = trim( arguments.MerchantProps.Username);
21                    break;
22                }
23
24                case 'payflowpro':
25                {
26                    gw.path         = "payflowpro.payflowpro";
27                    gw.GatewayID    = 1;//?????Not sure what this is for..Or if needed.
28                    gw.partner         = arguments.MerchantProps.partner;
29                    gw.vendor         = arguments.MerchantProps.payflowproVendor;
30                    gw.username     = arguments.MerchantProps.Username;
31
32
33                    gw.password     = arguments.MerchantProps.Password;
34
35                    break;
36                }
37            }
38
39            gw.TestMode         = arguments.MerchantProps.isInTestMode;
40            // create gw and get reference
41            getCFPayment().init(gw);
42
43            gw = getCFPayment().getGateway();
44
45
46            return gw;
47        </cfscript>

He asked if I had heard of the adapter pattern. When I told him no, he went into the technical details. We decided to dive into it and build a couple adapter classes, to trim down the function above. The first thing we did was create a base Adapter

view plain print about

1<cfcomponent displayname="Base Adapter" extends="lib.com.class.Class">
2    <cffunction name="process" output="false" returntype="Any">
3
4        <cfthrow detail="This is an abstract method. It must be overwritten."/>
5    </cffunction>
6
7</cfcomponent>

Don't worry about what the base adapter extends "lib.com.class.Class" that is just a base class that I like all of my classes to extend.You will notice that the Base Adapter has a function called process, that function is not meant to be called directly but implemented. Next we created a Base Payment Adapter

view plain print about

1<cfcomponent displayname="Payment Adapter" extends="lib.com.class.adapter.Apdapter">
2</cfcomponent>

This class extends the Base Adapter but doesn't do anything, that does not mean that it can't do anything, at this time it just doesn't. We then created a PayflowPro Adapter

view plain print about

1<cfcomponent displayname="PayFlowpro Adapter" extends="lib.com.class.adapter.payment.payment">
2    <cffunction name="process" returntype="void" output="false">
3        <cfargument name="data"             required="true" type="any">
4        <cfargument name="MerchantProps"     required="true" type="any">
5        <cfscript>
6            argumnets.data.path         = "payflowpro.payflowpro";
7            argumnets.data.GatewayID    = 1;//?????Not sure what this is for..Or if needed.
8            argumnets.data.partner         = arguments.MerchantProps.partner;
9            argumnets.data.vendor         = arguments.MerchantProps.payflowproVendor;
10            argumnets.data.username     = arguments.MerchantProps.Username;
11            argumnets.data.password     = arguments.MerchantProps.Password;
12        </cfscript>
13    </cffunction>
14
15</cfcomponent>

You will notice that it does exactly what the case statement does in the function above. That's correct. And you might think, man this is a lot code for nothing. What if you didn't use that the adapter here and you left the case statement alone. You would probably be okay if all of the clients in your application used PayFlowPro the same way. If you had a client that needed to add xyz to the PayFlowPro process, you might do something like this.

view plain print about

1case 'payflowpro_xyz':
2{
3    gw.path         = "payflowpro.payflowpro";
4    gw.GatewayID    = 1;//?????Not sure what this is for..Or if needed.
5    gw.partner         = arguments.MerchantProps.partner;
6    gw.vendor         = arguments.MerchantProps.payflowproVendor;
7    gw.username     = arguments.MerchantProps.Username;
8    gw.xyz            = "this is for my new client";
9
10    gw.password     = arguments.MerchantProps.Password;
11
12    break;
13}

That works! But now you have this long switch statement which personally I find it hard to sift through when debugging code. With the way that I have implemented the Adapter Pattern, you would do it something like this.

view plain print about

1<cfcomponent displayname="PayFlowpro Adapter" extends="lib.com.class.adapter.payment.payment">
2    <cffunction name="process" returntype="void" output="false">
3        <cfargument name="data"             required="true" type="any">
4        <cfargument name="MerchantProps"     required="true" type="any">
5        <cfscript>
6            argumnets.data.path         = "payflowpro.payflowpro";
7            argumnets.data.GatewayID    = 1;//?????Not sure what this is for..Or if needed.
8            argumnets.data.partner         = arguments.MerchantProps.partner;
9            argumnets.data.vendor         = arguments.MerchantProps.payflowproVendor;
10            argumnets.data.username     = arguments.MerchantProps.Username;
11            argumnets.data.password     = arguments.MerchantProps.Password;
12            argumnets.data.xyz            = "this is for my new client";
13        </cfscript>
14    </cffunction>
15
16</cfcomponent>

Now to show you the new an improved getGateway() function

view plain print about

1<cffunction name="getGateway" access="private" output="false" returntype="any">
2        <cfargument name="MerchantProps" required="true" type="struct" >

4            var gateway_props = {};
5
6            getAdapter( 'payment.' & arguments.MerchantProps.vendor ).process( gateway_props, MerchantProps );
7
8            gateway_props.TestMode         = arguments.MerchantProps.isInTestMode;
9            // create gateway_props and get reference

Seven Languages in Seven Weeks: Ruby Day 2

2010-12-28T10:12:00Z

Day two was little faster pace and we saw Ruby's magic and sugar according to to the author. We dove into working with structures, arrays and built a simple class. So far Ruby seems pretty easy and a little fun and its very easy to find help via google.

HW1 Day 2:

Print the contents of an array of sixteen numbers, four number at a time, using just each. Now, do the with each_slice in in Enumerable. The first part of this homework was a little bit challenging to do but the second part of the homework just seemed like I was cheating it was so easy.

Part 1

#Print the contents of an array of sixteen numbers, #four number at a time, using just each. Now, do #the with each_slice in in Enumerable. puts "Using the each method" #Create our array arrNumber = (1..16).to_a #Create a stack variable_stack = [] #Loop through the array arrNumber.each do |current_number| #Add the current number to our variable stack variable_stack.push( current_number ) #If the stack count is divisible by 4 #The ruby mod operator % if variable_stack.count() % 4 == 0 #Here I decided to out the stack using the method #Just for fun :) puts variable_stack[ variable_stack.count()-4, variable_stack.count() ].join(', ') end end

Output
Using the each method
1, 2, 3, 4
5, 6, 7, 8
9, 10, 11, 12
13, 14, 15, 16

Part 2:

puts "Using the each_slice method." puts "This seems like cheating" #Now for the each_slice method (1..16).each_slice( 4 ) {|a| p a}

Output
Using the each_slice method. This seems like cheating
1, 2, 3, 4
5, 6, 7, 8
9, 10, 11, 12
13, 14, 15, 16

HW2 Day 2:

The Tree class was interesting, but it did not allow you to specify a new tree with a clean interface. Let the initializer accept a nested structure with hashes and arrays. You should be able to specify a tree like this: { "grandpa" => { "dad" => { "child1" => {}, "child2" => {} }, "uncle" => { "child3" => {}, "child4" => {} } } }.

#The Tree class was interesting, but it did not allow you to specify a new tree with a clean interface. #Let the initializer accept a nested structure with hashes and arrays. #You should be able to specify a tree like this: #{ "grandpa" => { "dad" => { "child1" => {}, "child2" => {} }, "uncle" => { "child3" => {}, "child4" => {} } } }. class Tree attr_accessor :childNodes, :node_name def initialize( treeData ) #Define our class properties @childNodes = [] @node_name = 'root' #Alright I know this is not pretty but it seems to work case treeData when Hash #If the treedata coming through is a hash #loop through the hash treeData.each do |key,val| #set the node_name @node_name = key #Now we need to check the type of the val case val when Hash #if the val is a hash we are going to #loop through the keys val.each do |sub_key, sub_val| #create a new hash new_hash={sub_key => sub_val} #push to the @childNodes array @childNodes.push( Tree.new( new_hash ) ); end when Array #if val is an array loop through the elements val.each do |key,val| #check to see if our key is a simple value if key.size() != 1 if val != nil #if val is not nil or null add the val to the array @childNodes.push( Tree.new( val ) ); else #if val is nil or null add the key to the array @childNodes.push( Tree.new( key ) ); end else #if the key is not simple loop through it key.each do |sub_key, sub_val| #create a new hash and push is to our children array new_hash={sub_key => sub_val} @childNodes.push( Tree.new( new_hash ) ); end end end else #if val is simple then set the node_name to val @node_name = val end end when Array #if val is an array loop through the elements treeData.each do |key,val| if key.size() != 1 if val != nil @childNodes.push( Tree.new( val ) ); else Tree.new( key ) end else key.each do |sub_key, sub_val| new_hash={sub_key => sub_val} @childNodes.push( Tree.new( new_hash ) ); end end end else @node_name = treeData end end #this function works kind of like a debug #it will dump all of the node data def dump_nodes() p @childNodes end #I visit the entire tree of nodes def visit_all(&block) visit &block @childNodes.each {|c| c.visit_all &block} end #I visit just this node def visit(&block) block.call self end end

Building this class was really tricky because I needed to allow for nested hash and nested arrays. I know this isn't the cleanest class but it works. So lets try it.

First we will try the hash that the home provided.
{ "grandpa" => { "dad" => { "child1" => {}, "child2" => {} }, "uncle" => { "child3" => {}, "child4" => {} } } }

#create the hash family_hash = { "grandpa" => { "dad" => { "child1" => {}, "child2" => {} }, "uncle" => { "child3" => {}, "child4" => {} } } } #create a new tree ruby_tree = Tree.new( family_hash ) #Vist the top node puts "Visiting a node" puts ruby_tree.visit {|node| puts node.node_name } #Vist the entire tree puts puts "Visiting entire tree" puts ruby_tree.visit_all {|node| puts node.node_name}

Output Visiting a node

grandpa

Visiting entire tree

grandpa
uncle
child3
child4
dad
child1
child2

In this example we are going to add couple of arrays as keys in the hash under grandpa called Aunts and an array of puppies under sub child 11.
{"grandpa"=>{'dad'=>{'child 1' => {'sub child 11' => {"puppies"=>["rover","pluto"]}},'child 2' =>{}},'uncle'=>{'child 3' =>{},'child 4' =>{}},'Aunts'=>[{'Aunt 1'=>{'child 5'=>{}}},'Aunt 2']}}

#create the hash with nested arrays family_hash = {"grandpa"=>{'dad'=>{'child 1' => {'sub child 11' => {"puppies"=>["rover","pluto"]}},'child 2' =>{}},'uncle'=>{'child 3' =>{},'child 4' =>{}},'Aunts'=>[{'Aunt 1'=>{'child 5'=>{}}},'Aunt 2']}} #create a new tree ruby_tree = Tree.new( family_hash ) #Vist the top node puts "Visiting a node" puts ruby_tree.visit {|node| puts node.node_name } #Vist the entire tree puts puts "Visiting entire tree" puts ruby_tree.visit_all {|node| puts node.node_name}

Visiting a node

grandpa

Visiting entire tree

grandpa
uncle
child 4
child 3
Aunts
Aunt 1
child 5
Aunt 2
dad
child 1
sub child 11
puppies
rover
pluto
child 2

Last example we are going to take the hash above and make it an array.
["grandpa"=>{'dad'=>{'child 1' => {'sub child 11' => {"puppies"=>["rover","pluto"]}},'child 2' =>{}},'uncle'=>{'child 3' =>{},'child 4' =>{}},'Aunts'=>[{'Aunt 1'=>{'child 5'=>{}}},'Aunt 2']}]

#create an array with nested hashs with nested arrays family_array = ["grandpa"=>{'dad'=>{'child 1' => {'sub child 11' => {"puppies"=>["rover","pluto"]}},'child 2' =>{}},'uncle'=>{'child 3' =>{},'child 4' =>{}},'Aunts'=>[{'Aunt 1'=>{'child 5'=>{}}},'Aunt 2']}] #create a new tree ruby_tree = Tree.new( family_array ) #Vist the top node puts "Visiting a node" puts ruby_tree.visit {|node| puts node.node_name } #Vist the entire tree puts puts "Visiting entire tree" puts ruby_tree.visit_all {|node| puts node.node_name}

Notice that when we sent in the array that the top node is root.

Visiting a node

HW3 Day 2:

Write a simple grep that will print the lines of a file having any occurrences of a phrase anywhere in that line. You will need to do a simple regular expression match and read lines from a file. (This is surprisingly simple in Ruby.) If you want, include line numbers.

For my text file I create a file of this article http://sports.espn.go.com/nfl/news/story?id=5960674, Where Pennsylvania Governor: Postponement proves U.S. a 'nation of wusses' - from ESPN.com

counter = 1 file = File.new("readfile.txt", "r") while (line = file.gets) found_it = ( line ).grep /wusses/i if found_it.length>0 puts "#{counter}: #{found_it}" end counter = counter + 1 end file.close

Output
8: We've become a nation of wusses. The Chinese are kicking our butt in everything. If this was in China do you think the Chinese would have called off the game?

17: "We've become a nation of wusses. The Chinese are kicking our butt in everything," he added. "If this was in China do you think the Chinese would have called off the game? People would have been marching down to the stadium, they would have walked and they would have been doing calculus on the way down."

33: "What do you think [Hall of Fame coach Vince] Lombardi would say?" Rendell asked Monday. "He would say that we've become a nation of wusses."

Well Day 2 is done only 1 more day. And some far I really like Ruby.

Seven Languages in Seven Weeks: Ruby Day 1

2010-12-27T09:12:12Z

For Christmas 2010 my wife bought me Seven Languages in Seven Weeks which I ask for after seeing it on Ben Nadel's blog.

I Finished Day 1 of Ruby, so far its a very easy read. I learned how to output strings, a couple of different loops (while and until), Decisions (if and unless) and a little more. One of the things that I like about Ruby is the way it reads.

Example 1:

view plain print about

1x = 4
2unless x == 4
3 puts("This appears to be true");
4else
5 puts("This appears to be false");
6end

Day 1 HW

Print the string "Hello, World."

view plain print about

1#Print the string "Hello, World."
2print "Hello, World."

For the string "Hello, Ruby." find the index of the word "Ruby."

view plain print about

1#For the string "Hello, Ruby." find the index of the word "Ruby."
2phrase = "Hello, Ruby."
3puts phrase.index("Ruby.")

Print your name ten time

view plain print about

1#Print your name ten time
2i = 0
3while i <= 10
4 puts "Matt Graf"
5 i +=1
6end

Print the string "This is sentence number 1," where the number 1 changes from 1 to 10

view plain print about

1#Print the string "This is sentence number 1," where the number 1
2#changes from 1 to 10
3i=1;
4until i > 10 do
5 puts ("This is Sentence number #{i},")
6 (i+=1);
7end

Run a Ruby program from a file.

view plain print about

1#Run a Ruby program from a file.
2ruby /users/foobar/rubydemo/foo.rb

Bonus problem: If you're feeling the need for a little more, write a program that picks a random number. Let a player guess the number, telling the player whether the guess is too lower or too high.

CFBuilder Tip Whitespcae characters

2010-10-22T06:10:15Z

So today I was chugging alone and all of a su dden I had all of these Whitespace characters in my CFBuilder.

I could not for the life of my figure out how to remove them well thanks to Google and Raymond Camden I was able to fix it. To fix it you simple use these key commands "ctrl" + "." or if you are a Mac user "Command" + ".".
