+# Center The Cursor
+
+If you've moved the cursor to a particular line towards the top or bottom of
+the screen, you may want to center the screen on that line. This can be
+achieved by hitting `zz`. It is a quick way to center the cursor and ensure
+that you have an equal amount of context on either side of the line of
+interest.
+
+Take care to not mistake this for `ZZ` which will save and quit the buffer.
+
+See `:h zz` and `:h z.` for more details.
