Where can I find/unbind control shift space? (^⇧ + space)
Macs containing a trackpad (i.e. MacBooks) or with a trackpad attached allow Chinese Trackpad Handwriting. The shortcut ctrlshiftspace shows and hides this trackpad.



I have no clue what I have written.

To disable it enable Chinese Trackpad Handwriting and then disable/remove the shortcut for Show/Hide Trackpad Handwriting in System Preferences -> Keyboard -> Shortcuts -> Keyboard.
