I reset all my hotkeys to default just incase before asking, but in a few tutorials it cites using “Q” after putting in an operator to simply repeat it again, but when I hit Q in my node tree nothing happens. Tried a few times, even from scratch.

Somewhat unrelated but also: is there a way to get a new operator to automatically link to the selected previous operator? For instance, say I have a grid and want to put a mountain SOP on it. If I have the grid selected, and tab + type Mountain, and hit enter, it doesn't link, I have to do it manually. Any way to fix?

Hi,

Is your cursor over a SceneView when you press Q? Because it only works on operators added on the SceneView.

For #2, I don't think there is. There is a setting to place new tiles immediately, but that feature is broken to my knowledge.
