Let's not forget
QBar as it's my personal favorite, it also has optional
ButtonFacade support. It allows you to add a key-bind to it but it's a little flaky.
There is also
QuestClicks which seems a lot more robust, with the extra added ability to manually add or remove specific items from showing on the bar, via the in-game interface.
Currently no key-bind support but the author has stated that is a soon to come feature.
