Opening its main window and selecting 'View->Key history' from the You can tell if a script has the keyboard hook by Ensure that at least one script is running that is using the keyboard hook.you might still be able to make it a hotkey by using the following Some People Have Had Success Remapping Fn Functions via Autohotkey, and a Few Have Even Had Success Seeing the Fn Key. Level and that is not feasible through AutoHotKey. However automatingįeasible on the OS level: you would have to go down to hardware/driver So basically, automating fn-key is not feasible. Remap the secondary function of some key by remaping a key to send the OS, so you cannot actually 'remap' it in the OS. So the real deal about Fn-key is that it simply doesn't exist to the The signal that is sent when you press another key. The fn key is not supposed to send any signals. I don't get any response when I press the Fn key. One Poster on AutoHotKey Starts With a Rhetorical Questions

Pressing FN -> keyboard microcontroller waits for another key before sending any data.Pressing FN and F1 -> Scancode 0x9A -> operating system recognizes as VolumeUp key.

Pressing F1 -> Scancode 0x1A -> operating system recognizes as F1 key.

Most 'fn' keyboards (apple included) just process the key combinationīefore sending data, so pressing and releasing the fn key will do

Special keys (like the G15 ones): send standard (like the volume keys) or custom (depend on manufacturer) scancodes.

Modifiers (alt/option, control, windows/command and fn): sends modifier scancode byte + key scan code byte.Normal keys: send byte 0x00 + key scan code byte.Indeed, keyboard work as follow (values are just examples, behavior is Why is it Often Seemingly Impossible to Map the Fn Key? Sources - A) highrez forum post likely based on B) wikipedia post Not normally be remapped in software, unlike all other standard However,īecause the operating system has no notion of the Fn key, the key can Use standard keymaps designed for a full-sized keyboard. This allows the keyboard toĭirectly emulate a full-sized keyboard, so the operating system can In that it causes the operating system to see altered scancodes when The Fn key is a form of meta-modifier key, Interpreted by the operating system and combined with other Keyboard sends a scancode for the modifier itself, which is then For a standard modifier key, the microcontroller inside the Source: Microsoft Keyboards - F Lock Key What is the Fn Key? Some more detail:įn is not a normal keyboard key, such as the modifiers Ctrl, Shift andĪltGr. Keyboards released after September 2004, the keyboard will retain F Result, whenever the keyboard is reset, or loses power, the F Lock key Its state cannotīe controlled programmatically.

The F Lock key is a hardware switch in the keyboard. On a Similar Key, the F-Lock, Jason Tsang, Microsoft MVP, Says the Following: Source: UI Events KeyboardEvent Code Values - W3C Candidate Recommendation, 2017 This is typically a hardware key that does not generate a (see further down this answer).Īs the Fn key is usually at the hardware level, it would not be able to edit or disable this doing so at this level. Digging into remapping Fn combinations via a program like AutoHotKey, or digging into keyboard scancodes for Windows, one may be able to remap the offensive key combinations (Fn + Key).
