Like Windows, I want to hit Super+D to jump to the desktop or minimize all windows. I don't see command like that in Keyboard Shortcuts. Any idea?
I tried both Super+d and Ctrl+Alt+d to see the default for Ubuntu 14.04 and neither worked. Then again, I didn't bother to change the default setting. Try Ctrl+Super+d, thats what worked for me.
btw, the Super key for any computer with Windows automatically installed is the key that looks like the Windows logo.
