 'o' inserts a blank line after the cursor. 'O', before.
 
-'f' puts the contents of your previous cursor movement into the
-find buffer. If that movement was a forward movement, it brings
-the cursor back where it was. This allows for an efficient
-combination of movements and 'E'. For example, if you want to
-delete the next word, you type 'w', then 'f', then check your
-"F" buffer to be sure, then press 'E'.                  (cont.)
+'D' deletes "modifier" lines at the cursor.
