I want to allocate ctrl+alt+S to a shortcut in my IDE, however ubuntu uses this shortcut and it is not defined in the list under keyboard. Where do I set this shorcut?
I have found that since Ubuntu 16.04
Keyboard Bindings mostly doesn't show the windows management shortcuts (though occasionally it does, and I've never worked out what controls it).
However, I can check and modify them with
dconf or the GUI version
dconf-editor. Using this I see that
['<Control><Alt>s'] (lower case) is assigned to
/org/gnome/desktop/wm/keybindings/toggle-shaded: this is not the default entry, though I didn't set it explicitly.
You can change the entry to a different shortcut (eg
['<Shift><Control><Alt>s'] or restore the default setting by deleting it completely (
If this isn't the entry in your case, then you can use
gsettings to find other locations of the shortcut:-
gsettings list-recursively | grep -i \>s\'
This will find all shortcuts using the s key (plus a few spurious entries, perhaps - note that you can't be sure of the ordering of
<Alt> within the setting).
