I recently replaced my 2015 Macbook Air with a 2020 one (both British keyboards). On the new keyboard shift + 3 = £ and option + 3 = #. Previously the roles of these keys were reversed (shift + 3 = # and option + 3 = £). I use the # symbol much more often, so how can I change the key mapping back to what I am used to?

  • What Language do you have set in System Prefs > Keyboard > Input Sources? British 'standard' is to have £ on shift/3, US is on opt/3.

  • My language is set to British. So maybe my previous laptop was set to US. I don't want to change the language (I think it affects other keys) so maybe I will have to get used to this key. Feb 28 at 19:50

    What you have is the default standard for a UK keyboard. You can experiment by adding other languages to the input settings. Holding various shift/opt keys will show you the changes 'live' without having to commit…. or you can have both & swap between

  • There is no need to change your Language & Region setting, it has nothing to do with the keyboard mapping, and the keyboard mapping has nothing to do with spellcheck. Mar 1 at 0:13

Just change your Input Source to US or ABC instead of British. Nothing else of importance will be affected.
