How can you switch your current windows from horizontal split to vertical split and vice versa in Vim?
I did that a moment ago by accident but I cannot find the key again.
Vim mailing list says (re-formatted for better readability):
To change two vertically split windows to horizonally split
Ctrl-w t Ctrl-w K
Horizontally to vertically:
Ctrl-w t Ctrl-w H
Explanations:
Ctrl-w t makes the first (topleft) window current
Ctrl-w K moves the current window to full-width at the very top
Ctrl-w H moves the current window to full-height at far left
Note that the t is lowercase, and the K and H are uppercase.
Also, with only two windows, it seems like you can drop the Ctrl-w t part because if you're already in one of only two windows, what's the point of making it current?
