Hotkey for Cycle Window to close opened windows

By default Cycle Window uses ALT+TAB to be activated.
User has to hold down the ALT key to keep this dialog open.

Suggesting to add a new hotkey that would allow opened windows to be closed from within the Cycle Window dialog using nothing but keyboard.

User would have to use the same modifier used to open the dialog for this action.
For example, user can set this hotkey to something like ALT+DELETE

-So user would hit ALT+TAB to open the Cycle Window dialog
-Navigate to the item in list they want to close
-User would already be holding down the modifier ALT
-Then can hit DELETE key (which would be ALT+DELETE) and the window would close

Here is a similar post I made about this in the past to achieve this using mouse if anyone is interested.
