Whether you're timing the length of a presentation or how long it took you to run that ten kilometer race, try the Palmtop's Stopwatch function: it's pretty easy to use. Just press the CTRL+APPT keys and press F2 (Reset) to clear the clock. Press F4 to start the timer and F4 again to stop it. You'll see the time elapsed displayed to the 100th of a second. You could also use Stopwatch to time phone conversations, sales presentation or anything that you rehearse and that needs to fit into a given time slot.
