I need to be able to turn on an on-screen visual warning for cap for caps lock key. How can I do this? Can it be audible too?
AutoHotkey can do that and so much more!
Control panel...accessibility options
A utility program that gives an on-screen display and optional audible indication of the keyboard Caps Lock key state.
I just want to throw these two in the mix:
Try one of the following:
