Here's a tip: If you don't want to hold space the whole time but still get the maximum power, hold space, move your cursor off the screen while still holding space, and then let go of space (you may be at the bottom of the page, so just scroll back up if you are.) It should be working as if you were still holding space, just click another process and repeat to keep using this.
