+Output modes
 ------------
 
+The default output mode is Unicode/UTF-8 representations of ATASCII
+characters.
+
 **-a**
   Output raw ATASCII; no translation to the host character set. Must be
   used with redirection; **listbas** will not write ATASCII to the terminal.
 
-**-b**
-  Use bold, for color output. This may make it easier to read on
-  some terminals. Or, it may hurt your eyes...
-
 **-d**
   Print dots rather than Unicode/UTF-8 characters. Color and inverse
   video are still supported in this mode. Use this only if your
   terminal *really* doesn't support Unicode (e.g. **rxvt**\(1)).
 
-**-i**
-  Include the immediate mode command (line 32768) in the output.
-
 **-m**
   Output "magazine listing". See the **-m** option for **a8cat** for details.
+  Color is supported in this mode,
+
+**-x**
+  Output Unicode/UTF-8 representations of the XL International Character
+  Set, rather than ATASCII.

+
+**-i**

 **-n**
-  No color. Has no effect if **-a** or **-m** are in effect, since these
-  modes don't support color anyway.
+  No color. Has no effect if **-a** is in effect, since this
+  mode doesn't support color anyway. Disabling color does not
+  disable reverse video.
+
+**-u**
+  Use underlining for inverse video, rather than reverse video output.
