#Control-t keyboard shortcut to transpose characters

To develop:

web-ext run

To build:

web-ext build

Unfortunately there doesn't seem to be a way to get this to run in the address bar, so that'll have to be changed in Firefox itself: https://bugzilla.mozilla.org/show_bug.cgi?id=433972

In order for this to do anything, you'll have to make Alt the keyboard modifier rather than control: in firefox preferences about:config, change ui.key.accelKey to 18 from 17 (control). You'll also have to disable the ui.key.menuAccessKey which is by default set to 18; change it to something like 9999. In order for this change to apply, you'll have to restart the browser, which makes using this with web-ext hard. Did I ever have this working?
