Hotkey for extruding/moving along normal

While I had no idea that this was possible, I did it on accident today. I pushed some unknown button, and down in the bottom left corner of my screen, I see ‘along normal’ in place of ‘z axis’, etc.

Does anyone know how this happened? What is the hotkey to extrude/move a face along its normal?

I’m afraid that I’m using an unofficial build of 2.34 and im not sure whose it is…

Default behavior of 2.35 is to extrude along normal.

so…is there/will there be a way to grab and move a face along its normal?
