PopUp Time is a HackMaster extension which displays current time, OS version, battery voltage, free memory and Internet Time without leaving current application. There is a setup where you can choose the key stroke to activate it. (you'll certainly not choose the same stroke as for the other POpUp applications).
Current date, time or any date choosen from the calendar can be inserted into the current active field of the underlying application.
It can be started automatically each time you turn on your Palm device. Backlight can also be started automatically, always, or in the night time.
