The File Browser
****************
When reading or writing files, pressing ^T will invoke the file
browser. Here, one can navigate directories in a graphical manner in
order to find the desired file.
Basic movement in the file browser is accomplished with he arrow keys
and page up/down. The behavior of the enter (or 's') key varies by what
is currently selected. If the currently selected object is a directory,
the file browser will enter and display the contents of the directory.
If the object is a file, this filename and path are copied to the
statusbar and the file browser is exited.
