I started writing the basic commands in a comment, but it got kind of long. You'd best look at a reference.

I'd start with looking at commands that allow you to quickly move around in buffers first (/, f, t, w, e, b etc). Then start combining those with actions (ct", dw etc). Then "timesavers" such as macros and built-in conveniences (q, gqq, marks etc). The rest will come to you.
