Subject: [PATCH] shellActionModes: disable POPUP keybindings in lock screen
Certain keybindings should continue to work even when a popup
menu is on screen. For instance, the keybinding for showing
the app menu and the keyinding for showing the calendar are
examples.
This is achieved by putting in place a special "POPUP" action
mode, whenever a popup menu is active. This mode replaces
the (e.g., "NORMAL" or "OVERVIEW") action mode that was in place
for as long as the popup menu is active.
But those keybindings should not work when the user is at the
unlock dialog (which uses an action mode of "UNLOCK").
Unfortunately, right now they do.
This commit addresses the problem by using a compound action
mode when a popup menu is open at the unlock dialog (the bitwise
OR of POPUP and UNLOCK).
