Assigning a text string to a function key
I want to program a text string (my email address) to a function key so that when an app asks me to input my address, I can just press F19 and have the box fill in. This would generally be in Safari but it would be useful to work in most apps. I understand there are 3rd party apps that can do this, but I prefer to stay within the AppleOS. Can't Apple provide a way to do this?
