Apple Keyboard with TouchID choices

I really like my new keyboard with TouchID. I use it with a Mac Mini. I use the TouchID a lot for both access into the Home Screen of the Mac, and filling in passwords on websites. Are there actions that hard pressing the button does with besides locking the screen (back to the login screen)? Maybe something is available with the Cmd, Alt, Ctrl. I haven't been able to make it do anything with those.
