Super key + D shortcut doesn't work in show desktop functionality for me in Unity. I have searched and found solutions for adding a button in Unity launcher but I don't want that. I just want the keyboard shortcut to work for speed.

I found that Ctrl + Alt + D do something similar but gedit window doesn't bother to care for it.

That is odd, the keyboard shortcut works on my machine. I upgraded from 10.10. You should be able to find the appropriate action in keyboard shortcuts in the Control Center (my laptop is packed away atm, can't check). –  Erik Kronberg May 2 '11 at 9:37
    
I did a fresh install, and it doesn't work, other shortcuts work though –  Ashfame May 2 '11 at 9:59

go to Preferences -> Keyboard Shortcuts ->

  1. Window Management
  2. Sound
  3. Desktop -> Here you can add a new shortcut for that
  4. Accessibility

I will have to add a custom shortcut for it? Was it removed in Unity? And your instructions are for gnome, in Unity, we go to Power Button > System Settings (Control Panel) > Keyboard settings. And even if I am adding a custom shortcut, how would I associate it with the action? –  Ashfame May 2 '11 at 7:31
    
You need keyboard shortcuts and on mine its mode4+D to show desktop –  robin0800 May 2 '11 at 7:40

I went to Power Button > System Settings (Control Panel) > Keyboard Shortcuts and changed the shortcut key for the action "minimize all windows and set focus to desktop" to Super + D from Ctrl + Alt + D and now gedit obeys it too.

Its weird but its a bug that I certainly have no idea to reproduce. Another weird thing is I had to change it to Super + D & for some it works by default but since it seems to work fine now, I shall be marking this as the answer.

Some strange effect after that - Super-D mostly working, but first time Dash is displayed, it's a bug –  Extender May 2 '11 at 14:22

You have somehow saved another keybinding for that action. To go back to the default keybindings run this:

gconftool --recursive-unset /apps/gnome_settings_daemon/keybindings
gconftool --recursive-unset /apps/metacity/global_keybindings
gconftool --recursive-unset /apps/metacity/window_keybindings

There already is a keyboard shortcut that lets you see the desktop. It is just mapped to Ctrl + Alt + D. If you wish, you can remap it to Meta + D.

Search for Keyboard settings. Open Shortcuts tab. Move to Navigation. Scroll down until you see the option Hide all normal windows. Double click on it and press Meta + D. Now, Meta + D will show you the desktop from now on.

Just got to settings ---> appearance ---> behavior ---> add show desktop to the launcher

then try the keyboard shortcut again
