You can also move by whole lines, so zero moves to the beginning of a line, dollar sign moves to the end of a line, and the caret key moves to the first non-empty character on a line.
So, here, my cursor's right here; if I press 0, my cursor goes to the beginning of the line, dollar sign, end of the current line; and if I press caret, where, like, on what character will the curser end up?
