There should be a way to navigate to the context menus
for particular UI controls (maps, player info, spawn lists,
etc...) through the global menu. This would allow
keyboard access to those items, as well as benefit
novice users who might not have been aware of the right-
click context menus.
I suggest new top level menu items for the most
common UI controls. If there is more than one instance
of that type of control, then have the main menu item
drop down to display a list of each of those controls, and
from selecting those items, display the same set of
options currently accessible to the right click context
menu for that particular instance of the control.
