[root] Making the Back and Menu buttons vibrate on Samsung Galaxy Y

In this post I am going to show you how to make the menu and back buttons of your Samsung Galaxy Young vibrate upon touch.
Why do I need this, you ask? Everyone has a different taste for stuff and it may have come to some people's mind to want to have them vibrate upon touch.
There is no setting for this in any options menu, so we will have to do this manually by using a root browsing tool and modifying 4 lines of text on a file located deep in your system folders.

Requirements:
A rooted phone - How to root it? Click here.
A root browsing tool - e.g. Root Explorer 
So in this guide I will be using Root Explorer as a demonstration for all the steps, if you have no knowledge in browsing and modifying your system files then I would advise you to get Root Explorer and follow my instructions carefully to not ruin anything.

Step 1 - Finding the file for editing:
Now we are going to start up our root browsing app and go to the directory:
/system/usr/keylayout/

In there, we should see a file qwerty.kl:

1. Be sure to mount R/W
2. The file we are going to edit

Step 2 - Modifying the file:
Before everything, tap on the Mount R/W button at the top right corner so that we will be able to edit the files.
Now long press on the qwerty.kl file, you should get a popup with many options, so scroll down until you see the option "Open in Text Editor".

You should then see the following contents:

Now we need to modify 4 lines of text which are the following:
KEY 158 BACK WAKE_DROPPED
KEY 229 MENU WAKE_DROPPED
KEY 139 MENU WAKE_DROPPED
KEY 59 MENU WAKE_DROPPED
Find these 4 lines of text and at the end where you see WAKE_DROPPED, change that to VIRTUAL.

Final result:

Now press the menu button to get options to popup from the bottom and choose Save Changes.

And that's it, you are done. Now you just need to reboot your phone and enjoy the changes once it's back on.
To revert back, simply change the button names showed above back to WAKE_DROPPED.
