=> 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).
