I have arrived at 11.10, installed gnome-shell and wondered where I can bind my custom commands to keyboard shortcuts.
In Compiz I used the simple and efficient "commands" plugin. How to do that in gnome-shell?
You can set up your shortcuts in the Keyboard section of System Settings. You can either open System Settings in the Activities search or use the upper-right menu.
Then open Keyboard.
You'll see a section for Custom Shortcuts on the bottom left-hand side, if what you're changing is not already present in a section above.
These instructions may also be of use in Unity.
