Is there a toggle for the 'w' key rather than having to hold it down all the time to move? Better yet, is there an auto-walk mode to toggle? 

There doesn't appear to be but I hope one is added in a patch, such a simple quality of life that doesn't effect the character but so helpful to the player.  No idea why the decision was made not to have one programmed at launch.

Seriously, from the dawn of farking time we've had heavy objects at our keyboards to drop on the W key and save our hands from bonus carpal damage. Get it together already Obsidian, there's a thread in every game going back to .edu 90's message boards begging for autorun features.

I'm still waiting too. Isn't there a 'mod' or something? And in this day and age. Please at least add an option to make 'w' a toggle to auto-walk.
