Hello,
If for some reason these buttons are being used, and I just haven't found out what they are doing, then let me know, otherwise I would like to request that the "-" key and the "+" key get incorporated into the Action bar.

This would open it up to allow for more actions to be equipped on one bar at a time. As well as allow users to select the action they want via pressing those keys to do the action as well.

Currently the system goes from 1 to 0 on the keyboard, adding the - and + key would allow for 12 actions to be equipped per page.

Thanks so much for listening, looking forward to all the updates.
