Magic Keyboard function keys

Hello MrPerdu,

No, to my knowledge, you cannot assign text strings to function keys. An alternative would be to use the text replacement functionality found in Settings > Keyboard > Text Replacements.

With it, you can assign short strings to expand to a larger text. Personally, I prefix those shortcuts with "&" so that they do not conflict with anything.

For more information: Replace text and punctuation in documents on Mac - Apple Support.

You are welcome. Have a great week-end!
