The /B startup switch runs Keystroke in monochrome (black and white) mode.
Keystroke ordinarily detects the type of monitor being used and automatically uses the appropriate color settings for that monitor. The automatic settings may not work properly with some kinds of monitors.
Use the /B switch to force Keystroke to display screens properly on a monochrome monitor.
Usage:
Keystroke.exe /B.
This switch can be used with many Keystroke modules and utilities as well as the Keystroke program itself.
