I have 8 workspaces in use throughout the day arranged as 2 rows x 4 columns.
Workspaces are numbered logically from 1-4 for the top row left-right, then 5-8 for the next row.
I would like to be able to switch to a workspace using the keyboard combination Ctrl-num where [num] corresponds to number [1-8] on my numeric keypad.
Gnome/Compiz already allows me to switch workspaces via Ctrl-Alt-up/down/left/right or at least that is how I have configured it.
Finding a way to make the mapping and behavior described above however is still confounding me.
