Stop changing desktop keyboard shortcut at every distribution upgrade

[Teo]

The keyboard shortcut was once Super+D, which was fine because it was the same as in Windows.
Then in 12.04 it got changed to Ctrl+Super+D. Annoying.
Now in 12.10 it got changed again to Ctrl+Alt+D. Upsetting.

Are you going to change it at every d* distribution upgrade?
