Huh .. I have been trying to get the requested features implemented, but I can't
There are so many issues :
(1) FF does not support keyboard events on menus. (So, CTRL+ENTER on menu, can't be done
)
I can try to write some JS to achieve that, but .. I haven't been able to, yet.
(2) Multiple key-sequences (like CTRL+SHIFT+A+B) are not supported in FF. Again, JS can be used to define macros, but that would take some time.
So Ver.1.5 might be late. ( very late, actually
)
But, I might upload Ver.1.45 with some issues fixed like :
(1) The annoying info tag is gone.
(2) The search box can now be accessed with keyboard.
