A user parameter window that the programmer can set a value and a keystroke for commonly used functions.
for example, if you are programming a part with holes of varying depths you could set a letter with the parameter for the value desired. So for the .250 you would just type "Q" in the depth area of the auto feature, "W" for .500, "E" for 1.000 and so on. This function is a staple in modeling software.
