+# Close All Other Windows
+
+Opening split windows can be useful in a number of circumstances. Eventually
+though, you are going to want to go back to just one window. Generally when
+this happens to me, I navigate to each of the other split windows that I
+don't want and execute `:q`. What I want to do is essentially close all the
+other split windows except for my current one. Vim provides a single command
+for doing this. By hitting
+
+```
+<CTRL>w <CTRL>o
+```
+
+all other windows are closed leaving the current window as the only one on
+the screen.
+
+If you want this command to be able to work with windows containing modified
+buffers, you are going to want to have the `hidden` option turned on.
+
+See `:h CTRL-W_CTRL-O` for more details.
