If this has been done already, I apologize and ask for directions to the program.
I am requesting a keyboard lock requiring a 3-key combination that will lock the keyboard but not blank the screen or stop running processes. I have a network monitor running but I want to be able to leave my PC for short periods of time and be able to pop-in to view the screen and leave quickly and not worry that someone will come in and mess with my keyboard during those times I am not present. If I intend to leave for an extended amount of time, I can still invoke CTRL-ALT-DEL and lock the PC. The three key combo would ideally be any key combo present on my Dell Inspiron 8600 laptop. Obviously, the key combo can't be an existing one such as CTRL-ALT-DEL used by the system. Maybe CTRL and ALT should not be available as part of the key combo so as to avoid problems. All other key combos would be allowed. I appreciate your efforts on my behalf.
