Why use the mouse when you are already on the keyboard?

What if you want to be at the spot where you actually clicked the mouse?

That’s some arcane gobbledygook. I think you mean M-m

Yeah when I searched for "insert-mode" from another comment, the next suggested result was "insert-mode vim" and "insert-mode visual studio" (which IIRC is just aping vim), plus it's /c/programmerhumor so I had a feeling that it would be vim shenanigans.

Nope you're right, it was Fn+{{left arrow}} on mine. I don't use it often though

Ctrl+A does do that though if you wanted a Ctrl way of doing it
