=> THE VERY BASICS
Notations: ^X means <Ctrl> and X. The <Meta> key is <Esc> on most systems.
Exiting: ^G aborts almost any operation. ^X ^C will get you out of uEmacs.
A BUFFER is a named area containing a FILE being edited. Many buffers may
be active at once. Many WINDOWS may be active at once on the screen. All
windows may show different parts of the same buffer, or each may display a
different one.

=> FILE NAME COMPLETION
File name completion can be used with all file commands (find-file,
view-file, ...) but it works only under UNIX and MS-DOS. It is invoked
by a <Space> or <Tab>. If there exist more than one possible completions
they are displayed one by one. If the file name contains wild card
characters, the name is expanded instead of simple completion. Special
characters can be entered verbatim by prefixing them with ^V (or ^Q).
