Mac – How to press the Fn key using a PC keyboard on a Mac

You can accomplish this using AutoHotkey.

Here is a quick script:

File: Signs.ahk

#,::
Send {Asc 060}
return

#.::
Send {Asc 062}
return

When ran, this will allow you to send < and > by simply pressing the following keys:

• WinKey+, to send a <
• WinKey+. to send a >

NOTE: You do not need to map it to the WinKey, you can use Ctrl, Alt or any combination of those keys therein. Documentation for that can be found at the following KB article: Send/SendRaw/SendInput/SendPlay

You simply create the file w/ the .ahk extension, and execute it (or Right Click -> Open With... -> AutoHotkey.

This works (I tested it by switching my keyboard layout to ND and testing it. The reason this works is because AutoHotkey can send the ASCII equivalent to the < and > properly to any window that accepts that type of input.

I mapped them that way simply because on the English keyboard, they are on the same keys at those listed, but you can map them to whatever. However, i do notice that F1 through F12 will not work, given that the ND keyboard layout has no idea what those are properly.

Just a shot in the dark from this forum post, which is the only one I found that didn't suggest a stuck shift key (as your on screen keyboard displays caps lock on):

Try this trick. Go into Microsoft Word and type "tHANKS" and it will autocorrect it back to "Thanks" and your keyboard should be in sync with your monitor. I've noticed that my screen says the caps lock is off but my keyboard says it is on and after I try this trick it works again.

It sounds weird but it's got 38 upvotes and a whole lot of "thanks"; I do not know what the root cause is.
