In most window managers, pressing alt+space brings up the window context menu. Often the context menu items are navigable using
pgdn, and menu accelerators (so, say
pgdn might close the window)
In Gnome 3, you can still open the window menu with
space, but the navigation keys do nothing, and there don't appear to be any menu accelerators.
How do you add back in these menu accelerators?
If not, are there any other window managers that are comparable in features that have menu accelerators?
