I know that the keyboard shortcut to use for the Euro symbol is Option + Shift + 2. But I'm now using the
$ key, why can't I just re-assign or reprogram the Shift + 4 key combo to give me €?
Does anyone know a way this can be done?
Two apps for remapping keys are Ukelele and Karabiner.
Also the Dutch keyboard layout is the same as US but has € at Option 2, if that is easier.
You can also set up a text replacement in system preferences/keyboard/text/replace with, so that for example $$ gives you €.
