Toggle sprint means you only need to tap the key once to sprint and tap again to stop. If you manually stop via non-forward movements it just cancels sprint. It's not an 'always run' switch. 

I have running set to toggle. But the game resets to 'walking' in a frustrating number of circumstances. If I am sprinting and then come to a stop, and then move again I will be in 'walking' mode. I have to toggle sprinting back on. This is really obnoxious.

I'd prefer if it just turned sprinting ON until I turn it OFF. Am I missing a setting? Please help. 

Is this what you guys do?

Do I really have to tap sprint every time I stop moving?
