+# Horizontal to Vertical and Back Again
+
+If you have two Vim windows open with a horizontal split and you want to
+quickly switch them to be vertically split, you can type the following two
+key bindings:
+
+```
+Ctrl-w t
+Ctrl-w H
+```
+
+To go from vertically split windows to horizontally split windows you can
+instead use:
+
+```
+Ctrl-w t
+Ctrl-w K
+```
