USING EMACS WITH X
</B></P>
<P>emacs has been tailored to work well with the X Window System. If you run
emacs from under X windows, it will create its own X window to display in. You will probably want to start the editor as a background process so that you can
continue using your original window.
</P>
<P>emacs can be started with the following X switches:
</P>
<TABLE>
<TR><TD>
_rn name
</TD><TD>
Specifies the program name which should be used when looking up defaults in
the user's X resources. This must be the first option specified in the command line.
</TD></TR><TR><TD>
_name name
</TD><TD>
Specifies the name that should be assigned to the
emacs window.
</TD></TR><TR><TD>
-r
</TD><TD>
Display the emacs window in reverse video.
</TD></TR><TR><TD>
-i
</TD><TD>
Use the "kitchen sink" bitmap icon when iconifying the
emacs window.
</TD></TR><TR><TD>
_font font, _fn font
</TD><TD>
Set the emacs window's font to that specified by
font. You will find the various X fonts in the
/usr/lib/X11/fonts directory. Note that emacs will only accept
fixed width fonts. Under the X11 Release 4 font-naming conventions, any font with
the value m or c in the eleventh field of the font name is a fixed width font.
Furthermore, fonts whose name are of the form
width¥height are generally fixed width, as is
the font fixed. See xlsfonts(1) for more information.
</TD></TR><TR><TD>
</TD><TD>
When you specify a font, be sure to put a space between the switch and the
font name.
</TD></TR><TR><TD>
_b pixels
</TD><TD>
Set the emacs window's border width to the number of pixels specified by
pixels. Defaults to one pixel on each side of the window.
</TD></TR><TR><TD>
_ib pixels
</TD><TD>
Set the window's internal border width to the number of pixels specified by
pixels. Defaults to one pixel of padding on each side of the window.
</TD></TR><TR><TD>
_geometry geometry
</TD><TD>
Set the emacs window's width, height, and position as specified. The
geometry specification is in the standard uformat; see
X(1) for more information. The width and height are specified in characters; the default is 80 by 24.
</TD></TR><TR><TD>

</TD></TR><TR><TD>

</TD></TR></TABLE>
<P>You can set X default values for your emacs windows in your
Xresources file; see xrdb(1). Use the following format:
