When you are happy with your work, press ctrl-W and enter a filename to write. You can also press ctrl-R and read in a new file, overwriting your masterpiece.

+                    This is beta software, if not alpha. It kinda works, but there will be issues. Feel free to help out with a patch, or by filing bug reports.
+                    Known issues include:
+
+                    * Editing long lines will blow up. Don't try to edit anything longer than the terminal is wide.
+                    * There is no fullscreen editing, so verbatim blocks in twig will probably not work well either.
+                    * Comments are not preserved.
+                    * Files are overwritten without confirmation.
+                    * There is no command mode, no search.
+                    * Some things just don't work yet.
+                    * Unhandled keys will appear in the bottom left of the screen with a delay.
+                    * Folding is not yet implemented.
