True.  Let's see existing keybindings related to `q':

C-x q   runs the command kbd-macro-query
C-x C-q runs the command toggle-read-only
C-x 0   runs the command delete-window
C-x 4 0 runs the command kill-buffer-and-window

The latest is the closest, so a possible keybinding
for `quit-window' would be `C-x 4 q'.
