From Kee 2.0:
Ctrl+Shift+1 - Show Kee popup panel
Ctrl+Shift+2 - Show matched logins or login to KeePass as applicable (KeePass must be running on your computer)
Ctrl+Shift+4 - Generate a new password
Ctrl+Shift+6 - Force detection of forms on this page
From Kee 2.2, the up/down arrows, enter, escape, tab and the context menu key will do useful things - details pending when someone has time to write it here.
