PREVIOUS WINDOW

 Puts the cursor at your last position in the previous window, if you are
 using two or more windows.

 For example, if you are using three windows like this:

    +-----------------+    From the top window, the cursor returns to
    |  [] cursor      |    your last position in the bottom window.
    |_________________|
    |      []         |    From the middle window, the cursor returns to
    |_________________|    your last position in the the top window.
    |[]               |
    |                 |    From the bottom window, the cursor returns to
    +-----------------+    your last position in the middle window.

 If you are using only two windows, PREVIOUS WINDOW, NEXT WINDOW, and OTHER
 WINDOW are the same.
