TSR
Abbreviation for terminate-and-stay-resident. A TSR program runs "in the
background." Most TSR programs implement a predefined key combination
(sometimes referred to as a hot key) that allows you to activate the TSR program's
interface while running another program. When you finish using the TSR
program, you can return to the other application program and leave the TSR
program resident in memory for later use. TSR programs can sometimes cause
memory conflicts. When troubleshooting, rule out the possibility of such a
conflict by rebooting your system without starting any TSR programs.
