In X11, is there a way to configure the keyboard so that the behavior of the context menu key is as follows:
- KeyPress opens the context menu.
- As long as the key is held down, the menu stays open and can be navigated with the arrow keys.
- KeyRelease executes the highlighted action (or closes the menu, if nothing is highlighted).
Ideally, there would also be a way to return the menu to the initial "nothing highlighted state" using only the arrow keys as well.
Is this possible?
