How to setup KeyPad
KeyPad works like any other physical bluetooth keyboard. You may need to refer your device documentation for instructions on connecting a bluetooth keyboard. Please send me email if you have any issues. My email is tools@toolbunch.com
Launching KeyPad when you need it next
You can setup additional devices, and their hotkeys in the preferences screen. Go to the toolbar menu and click preferences.
Sometimes the toolbar icon gets hidden behind the menu. If this happens, move to another application (like finder) to make the toolbar visible, and while pressing the command key on your keyboard drag the KeyPad Icon to a better location on the toolbar.
