Too complicated to use Rated 2 out of 5 stars

In only need uppercase / lowercase, this does that.

However, this is much too complicated addon for that purpose and this reserves many shortcut keys which I need for other addons. So in UNINSTALLED.

FEATURE REQUEST:
With MS Word 2003, Shift-F3 changes case. Could you please implement that shortcut key to this addon? And make it possible to easily switch-off all other shortcuts.
