    A program installed to be memory resident so that you can always execute it by pressing a special key, called a hot key. When you press the hot key, the pop-up utility appears, regardless of which application you are currently running. When you exit the pop-up utility, the system returns you to your previous program.

    In DOS systems, pop-up utilities are also called TSRs.
