WindowDeck
Ctrl+H hides the key hints
Press Ctrl+H in WindowDeck to hide or show the strip of key hints at the bottom. The window gets shorter, and the cards stay where they are. WindowDeck remembers your choice.
While the hints are hidden, a small "Ctrl + H Hints" label shows at the right of the top bar. It tells you how to get them back. You can also switch them on the WindowDeck Settings tab, with "Show key hints".
