Auto-move forward button

[Tacker]

A button that, when pressed, will move your character forward and keep moving until it gets on an obstacle or you press again that button.
Or, it can be an option to activate. Under "Movement" menu. Something like that: Movement -> Move forward.
Both of them in order to replace keep pressing "W" button or keep left clicking. They are such a pain when you travel in distant areas.

I don't think there is already such a button and I believe it would be useful. Specially, when you pull your sturdy sled for loooong distance and you move like a snail. You know what I mean...

you can do this (albeit a ghetto fix) by alt tabbing while holding w. stop moving forward by hitting w again, but this messes up the wasd keys for a little bit.
