I just installed geanylua and was able to set keybindings for lua plug-in scripts. Very nice. But, one little omission I notice is that the keybinding shortcut doesn't show up in the menu item for that plug-in.
On a related topic, I set "Search --> Find" from Ctrl-f to Ctrl-Alt-f (using Ctrl-f for the incremental search field in the toolbar), but it still says Ctrl-f in the menu item shortcut (note: everything *works* as it should, it's just the shortcut menu item text that's incorrect).
