About FN Key Lock
FN Key Lock is a Windows utility that simulates a hardware-style lock for the F1 through F12 keys. Users can control the lock through customizable controls, and the program displays notifications to show when the lock state changes. The function is aimed at situations where the top-row function keys need to remain in a chosen mode instead of changing behavior unexpectedly during regular keyboard use. By providing a software control and visible status, FN Key Lock offers a way to manage this behavior on systems without relying on a dedicated keyboard switch. Custom controls operate the lock, while notifications provide visible feedback about its state.
