Playing a TAG game on a computer without a real keyboard will require selecting a virtual TAG keyboard.

When starting a TAG application the very first time, if the app detects a touch screen, it will presume a virtual keyboard is necessary. This can be reversed by clicking the FILE menu and selecting Prefers and selecting --- for the keyboard. Don't forget to SAVE the changed preferences.

A stylus (basic Pen = Capacitive style) will improve accuracy in touching virtual keys. Search google for "tablet pointing stylus".

More information on TAG application preferences can be found in Preferences Guide
