Set talents to "automatic" without right-click

[kazak]

I'm playing ToME on my macbook (osx 10.6). I've seen mentioned on here several times in the past that right-clicking doesn't currently work in OSX (along with other general stability issues). Not sure if the SDL issues will be worked out in the next te4 release, but if not I'd really like to see another way to set talents to automatic without right-clicking. Like an option in the keybinding menu. Some classes just lose a lot of charm without autocast (rogues, mages, paradox mages, etc...).

Thanks!
