How do I create custom accents?
I saw online that I could go into /System/Library/Input Methods/PressAndHold.app/Contents/Resources/ and edit the file Keyboard-en.plist and add:
<key>Roman-Accent-t</key>
<dict>
<key>Direction</key>
<string>right</string>
<key>Keycaps</key>
<string>× ÷ √ π ∴ ∵ ≈ ≠ ∞</string>
<key>Strings</key>
<string>× ÷ √ π ∴ ∵ ≈ ≠ ∞</string>
</dict>
...or whatever characters I prefer.
First, I'm not sure where this goes in the code (e.g. top, bottom, etc). Second, each time I try to edit, it tells me I must make a duplicate to do so. Upon editing a duplicate, I was left with a .txt file instead of a .plist file, and therefore I was not able to replace the previous "Keyboard-en.plist".
Any help concerning how this would be done is greatly appreciated! Thanks!
