TIP: Using the zoom feature can make it easier to fasten bolts.

The Zoom feature is not mapped to a key by default. I map it to 'Z'.

If you find that your mouse cursor drifts off the bolt while using the wheel to fasten or unfasten it, try using zoom. Mouse movement is greatly (~75%) reduced, so it is far easier to keep your mouse centered on the bolt. The effect is strong enough to counteract high mouse sensitivity when leaning, so the two keys work well as a combo. This wasn't obvious to me, so I share it for anyone who hasn't tried it before. It works really well.
