No advice on moving from line to line? Word and character movements are great (and well worth learning), but how do you suggest moving to just the next line without spamming `w`?

These move up/down one character, even if it is the same line wrapped over. Really beneficial for things like LaTeX editing.
Much of the time, I want to go to a specific part of the next line. In which case, let's say I want to go to the parse function, I'll do "/par<enter>".
and - to move 1 line up. Combine with a number, 4+ to move down 4 lines, complementing 4G or :4<CR> to move to 4th line.
