  • KeyboardMaestro solved my problem, but I'm looking for a solution that doesn't require a third-part software. Thanks!

Create a plain text file with this in it (in TextEdit, use Format > Make Plain Text):

    "~d" = ("insertText:", "ð");

Call it DefaultKeyBinding.dict (make sure to uncheck “When no extension is provided, use .txt”), and save it in ~/Library/KeyBindings/. (You can press Command ⌘+Shift ⇧+G and paste that path.)

The "~d" means Option-D, and the ("insertText:", "ð") means it will insert a ð character instead of ∂.

You will have to restart your applications in order for this setting to take effect.

  • I have no KeyBindings in my Library folder.. I use OSX 10.9.4

    @hiru: Then make that folder yourself.

Another solution is to create a custom keyboard layout. I can easily type symbols like , , 💩, and with my custom layout.
