How can I enable the standard ctrl-n/ctrl-p shortcuts to navigate dropdowns in Mac OSX?
In OSX, ctrl-n/ctrl-p are are generally accepted as substitutes for up/down, and those keyboard shortcuts can be used to move the selection up/down in a dropdown menu. Safari and Chrome properly move the dropdown selection, but Firefox does not.
Firefox correctly moves the textarea cursor up/down using ctrl-n/ctrl-p. It just does not work on dropdown menus.
