F11 simply doesn't cut it, creating messy borders at the edge of the screen.
This is my goal: hiding all windows using a keyboard shortcut.
This is a newer version of my last instructable, in this one you only need to download one application (Show desktop), if you already have Quicksilver.
Step 1: Downloads
1) Show Desktop
This will hide all the windows
We will use Quicksilver to create a HotKey Trigger
(that means we'll tell a keyboard key we choose, its new job is to show desktop)
Step 2: Show Desktop
When you press on the Show desktop icon in the Dock it will hide all applications (depending on the preferences).
go to the preferences in Show Desktop, and see the different options, this is something you should do with every new program you get so as to use it the best way you can.
I set my prefrences this way (see picture):
Step 3: Quicksilver
Go to the triggers window (see image 1) and make sure you're in "Custom Triggers" (No.1 in image 1).
now press the plus sign (No. 2 in image 1) and choose "HotKey, this will open a menu (see image 2).
Start writing "show desktop" until it shows you the correct application, leave the action as "open", and save.
You will return to the Triggers menu, now press on the area I can only describe as No.3 in image 3.
A drawer will open, press on edit (No.4 in image 4), then press the F8 key (or any other key you want).
close the triggers window.
