Navigating Vertically

Vertical motions move the cursor up and down the document that is being edited, and are critical for efficiently navigating a document.

We start with a few motions that move the cursor to absolute positions in the buffer:

ggcursor to line N, default first line
Gcursor to line N, default last line
%find the next (curly/square) bracket on this line and go to its match, or go to matching comment bracket, or go to matching preprocessor directive.
