Simulate that i hold an random Key.

n1mare,

I’m sorry, I don’t understand what you would like to do. What is it exactly that you would like to have happen? Please provide an example.

n1mare,

so you would like to have a “Shift Lock” or a “Control Lock” function — is that right? You would like to have that instead of a Caps Lock? Or you would like, for example, to have a Control key act as a “Control Lock”? As I’d asked before, please provide an example of what you would like to have happen.

n1mare,

if you still have KeyRemap4MacBook installed, you can set up a “Control Lock” function through e.g. checking the “▼ Change Control_L Key (Left Control) → Control_L to Sticky Control_L” checkbox — this would turn the left Control key into a Control Lock key.

Alternatively, you could open the Accessibility pane of System Preferences, select Keyboard on the left-hand side, and then check the “Enable Sticky Keys” checkbox to have all of your modifier keys act as Lock versions. If you choose this option, then I’d recommend also checking the “Show Accessibility status in menu bar” checkbox.

I don’t know of any program that will set a random key to be a Lock key — the choices in KeyRemap4MacBook are all for specific keys, not for making one random selection out of all of the keys.
