To change two vertically split windows to horizonally split

    ^Wt^WK
Horizontally to vertically:

    ^Wt^WH
where ^W means "hit Ctrl-W". Explanations:

    ^Wt     makes the first (topleft) window current
    ^WK     moves the current window to full-width at the very top
    ^WH     moves the current window to full-height at far left

^Wx is really difficult to type, but super useful when you have a model/controller in your left pane, and a spec on the right. leader ww and they swap. (also swaps horizontally split buffers) boosh
