On: Vim anti-patterns

[vectorpush]

<j><k><k><i>

OR

<up>

I prefer a single key to four, even if I have to move my hand off the home-row.

[djacobs → vectorpush]

How often is it that you want to perform this move (edit the character immediately above the cursor, but not in block mode)? If you're moving horizontally by a single space, you have backspace and delete for single-character moves (which are an edge case). If you're intending to add new content in a new line, why not <Esc>O?
