			Alt is not a selfcast key by itself at all. It's just that default keybinds have a "cast <this> from main action bar on yourself" functionality, and it's set to alt+nuimber combinations. Check keybinds in menu, it's like:
Action button 1   - 1
Action button 2   - 2
Action button 3   - 3
etc...
Self cast action button 1   - alt+1
Self cast action button 2   - alt+2
etc.
So if you don't touch default settings you have selfcasting available on the main action bar, but that's about it. You can't bind E to a buff and expect alt+E to self buff you automatically. Need to set up macros for that.
