I accidentally started Read Aloud using the gesture and I couldn't figure out how to turn it off because it didn't open the Reading control. I tried selecting the "Read aloud" option in the window's menu to get the control to show up, but it didn't do anything while it was already reading.
I ended up closing the window to stop it. Turns out I could have used the "stop" gesture to stop it, but I didn't know what it was without looking it up.
I still think the gesture should open the reading control like the menu option does.
EDIT: nevermind. I just read that this is a known issue.
