Truning Off Switch Labels in Driver?

This is probably a basic question, but how do I turn off the labels and arrows over the switches when in Driver? I'm talking about the white text that gives the name/number of the switch and the red/green arrows indicating alignment. (I'm calling them switches, but I believe they're called "points" in the UK.) When I'm running AI trains, I don't necessarily need to see that info and can use the map if I do. Thanks!

This is not a basic question because it's documented, or more buried with everything else somewhere, but not off by default. Off should be the default and on optional.
