Here's what I do: In the Controls menu under infantry movement, bind "fast forward" to the W key. This lets you sprint without holding shift. Unbind normal forward movement from W. You can still jog with the up arrow key. Next, find a credit card, finger nail clippers, or anything small and flat to jam down the W key by fulcruming against the keys above it. DIY autorun completed. Seriously, this is the biggest missing feature.
