Yet another post that reads like four shakespeare characters who come out in the middle of the play to talk about something completely unrelated for comic relief
There's a little + that you can click on the icons.
Or, you can use the keyboard arrows and spacebar.
Not sure if there's others.
Edit: Just found another one actually. Middle-clicking selects without opening.
This works better than the little + on the icons because the + behaves like a "ctrl-click."
Ulululululululululu.
