[SOLVED] Left / right starts playback

Suddenly, when the transport is stopped, if I use left / right arrows to move the playhead it will start playback.

When transport is stopped, I’m used to left / right just moving the playhead without starting playback. I guess I accidentally changed some setting by hitting the wrong shortcut, but which one? How do I restore “normal” (at least for me) playhead behaviour?

Found it: I accidentally hit CTRL-7 (intending ALT-7) to enable Transport > Auto Play
