It is indeed. I need two keystrokes to move from an arbitrary positions in an arbitrarily long file to the exact spot I need to be.

I use it all the time, in fact. Multiple times an hour. It's muscle memory now for me, while reading/navigating code, to automatically do `ma` or `mb` etc.

At some later point I realise "let me read the function definition again" and then I do `'a` or `'b`, etc.
