The page editing quicktags conflict with the shortcuts used for keyboard
navigation in Mozilla Firefox. While editing a page in a wiki, I might decide I
want to go somewhere else, and thus press ALT-D to focus my cursor in my Firefox
address bar -- but instead the wiki asks me if I want to delete the page.
I have "solved" this by unchecking the "Show edit toolbar" option, but some
shortcuts are still clobbered. ALT-F focuses the Wiki search, instead of
accessing the browser's File menu.
