settings:: window-manager:: keyboard settings menu: keyboard shortcuts cannot be edited by keyboard alone - e.g. Enter or Space opens the sub-dialog but immediately closes it, auto-assigning the key (Enter or space) no way to delete an assignment/entry either. the sub-dialog size is not big enough / not auto-sized - only leftmost column of the shortcut table is visible.
See also bug 2464, which is the converse of this bug: in the Keyboard > Settings editor, you can't have Enter as a keybinding because it activates the buttons. (Perhaps it would be better to have a single "keybinding editors aren't consistent" bug.)
this bug happens because the composition window is opening on the activate signal of the shortcuts list and when the key-released signal is sent the composition window is the only that catches it and interprets that as the new shortcut. We need to find a way to tell the composition window to ignore that signal.
This is kindof fixed in the current git master branches, except that conflict dialogs don't work with the keyboard because we grab it...
