To avoid ambiguity in this question I will use
key to mean a plist-dictionary-key (look-up string); and key to mean a button on your keyboard.
This answer to another question identified a great way to edit the special characters you can insert using the press-and-hold method on your keyboard.
You can edit the
Keyboard-xx.plist files of the
PressAndHold.app to add your characters to existing press-and-hold keys. The plist dictionary
keys for each press-and-holdable key look like this:
<key>Roman-Accent-A</key>, etc. but if you want to add some press-and hold characters to a number key, or a punctuation key then you need to know the
key name for the dictionary in order to add it.
I want to add press-and-hold characters for the 2 and 3 keys and possibly others, I have tried the following formats for the
key names in the plist file:
2 Number-2 Roman-Accent-2
None of these add a press-and-hold popover for the 2 key. What are the correct
key names for all of my keyboard keys that I can add in
