| use hardware keys | if you turn on this function, the hardware keys of your PDA will be used as described in Keys |
| when application is locked - lock keys also | depending on your PDA and your personal preferences you might want to use the keys even when the screen is locked; if you have a PDA with very sensitive keys, turn off the keys when you lock the application |
| when application is locked - use center key to start/stop training | if you turn off all the keys while in a training or competition, you can still use - the center (also named "enter") key to start or stop the training - and the left function key to start a new lap; with most PDAs not turning off these two keys is okay because it needs some power to press them while you have the device in your pocket |
