⌃F2 only works after you have hit ⌃F1 once to “Turn keyboard access on or off”. If you hit ⌃F1 again, it will stop working. It’s probably not working for you because you hit ⌃F1 sometimes. You might be hitting it accidentally or because you use it to do something else – I use ⌃F1 to start recording a Quick Macro in Keyboard Maestro.
