This will be a tracker for key and mouse bindings.  I am avoiding bugs about "I
want a keybinding to do X" (though one or two may have slipped in), and am
trying to collect bugs about keybindings that already exist but don't work as
expected.  I will start this off with the following dependencies in a minute:

 90290  not allowed to move immediately after double-click-roll-up
 91538  allow multiple keybindings for the same function
103516  super bound to other action ("compose"), but still used for modifier
103584  keyboard grab not released under heavy load
108775  should be a way to bind extra mouse buttons to actions
112560  keybindings have to be fully released before the grab ends
116041  ctrl-alt-arrow acts on wrong screen for multiscreen  
117995  alt-click doesn't raise when over some window buttons
136488  switch windows by XF86XK_RotateWindows keysym by default
143154  key release events not captured, leading to a stuck grab
151554  half of modifiers are hosed by upstream Xorg change
152169  temporary lock ups on all window controls
154297  custom keybindings disables keyboard
