Wow. This is fun. I've only been using the software for a few months, but I had no idea. Very handy feature.
For anyone else not in the know like I was not, apparently you can perform commands in Logos by holding down the right mouse button, moving the mouse curser in a particular pattern, and then releasing the mouse button. For instance, to transition to reading view whatever it is you're reading, click and hold the right mouse button, move the mouse up and to the right diagonally, release the mouse button, and bam, reading view. Doing the opposite, down and to the left diagonally hides reading view. There are others as well, feel free to look them up in the Logos help tab within the software. Very cool.
