About this extension

Many terminal applications including emacs, and from this lineage, most MacOS inputs, support control-t to transpose the characters around the cursor. Firefox currently lacks this feature, though they would be willing to support it: https://bugzilla.mozilla.org/show_bug.cgi?id=433972

In the meantime, this add-on adds the control-t shortcut to inputs and contenteditable elements.

Release notes for 1.1

1.1: Add handling for a newline after the cursor. The two characters before the newline will be transposed.

Also discovered a bug: transposing characters does not work with control-z undo.
