Sometimes, the "a", "b" and "v" keys do unexpected things.

*It seems like sometimes *a, b, and v keys behavior is normal, sometimes it BUGS.

If you press a in chat/signs, it resets the chat/sign text and writes a.

If you press b in chat/signs or walking, it toggles narrator (Active, Chat, System, None).

If you press v in chat/server informations it pastes the last stuff you CTRL + C'ed.

It's so annoying, I cannot type almost anything because a and b are some letters that you use very much.
