So... while watching, you'll wonder: How am I clicking so quickly? It's actually very simple: I assigned the “Select” function to the SCM Up key as well.

If you've watched Borderlands 2 speedruns, you're already familiar with this feature. If not, let me quickly explain: When you scroll the mouse up, the game counts EVERY tiny scroll. This “clicking” method has a big benefit: your finger won't get as tired as with regular clicks, which means you can keep trying to speedrun for longer! I highly recommend this type of click, at least in the Alley% category.
