Keys: +, -, Enter
+ and Enter both move down to the first non-blank of the next line. - moves up. Useful for navigating indented code line-by-line without ending up mid-indent.
j moves down a line but keeps your column. So in indented code you often land mid-indentation. + (and Enter) move down a line and also land on the first non-blank — exactly where the code starts.
