 DESCRIPTION
-    rxvt-unicode, version 6.0, is a colour vt102 terminal emulator intended
+    rxvt-unicode, version 8.2, is a colour vt102 terminal emulator intended
     as an *xterm*(1) replacement for users who do not require features such
     as Tektronix 4014 emulation and toolkit-style configurability. As a
     result, rxvt-unicode uses much less swap space -- a significant
     advantage on a machine serving many X sessions.

 RXVT-UNICODE VS. RXVT
     Unlike the original rxvt, rxvt-unicode stores all text in Unicode
     internally. That means it can store and display most scripts in the
     world. Being a terminal emulator, however, some things are very
     difficult, especially cursive scripts such as arabic, vertically written
     scripts like mongolian or scripts requiring extremely complex combining
     rules, like tibetan or devenagari. Don't expect pretty output when using
     these scripts. Most other scripts, latin, cyrillic, kanji, thai etc.

+    should work fine, though. A somewhat difficult case are right-to-left
     scripts, such as hebrew: rxvt-unicode adopts the view that bidirectional
     algorithms belong into the application, not the terminal emulator (too
     many things -- such as cursor-movement while editing -- break
     otherwise), but that might change.
     If you are looking for a terminal that supports more exotic scripts, let

     terminal emulator. In fact, the reason rxvt-unicode was born was solely
     because the author couldn't get "mlterm" to use one font for latin1 and
     another for japanese.
     Therefore another design rationale was the use of multiple fonts to
     display characters: The idea of a single unicode font which many other

 OPTIONS
     The rxvt options (mostly a subset of *xterm*'s) are listed below. In
     keeping with the smaller-is-better philosophy, options may be eliminated
     -display *displayname*

         which enables applications to easily embed a terminal.
         Right now, rxvt will first unmap/map the specified window, so it
         shouldn't be a top-level window. rxvt will also reconfigure it quite

         It might be useful to know that rxvt will not close file descriptors
         passed to it (except for stdin/out/err, of course), so you can use
         file descriptors to communicate with the programs within the

         used or not.
         Here is a short Gtk2-perl snippet that illustrates how this option
         can be used (a longer example is in doc/embed):
            $rxvt->signal_connect_after (realize => sub {
               my $xid = $_[0]->window->get_xid;
               system "rxvt -embed $xid &";

         useful if you want to drive rxvt as a generic terminal emulator
         without having to run a program within it.
         If this switch is given, rxvt will not create any utmp/wtmp entries
         and will not tinker with pty/tty permissions - you have to do that
         yourself if you want that.
+        As an extremely special case, specifying -1 will completely suppress

         Here is a example in perl that illustrates how this option can be
         used (a longer example is in doc/pty-fd):
            use IO::Pty;
            # now communicate with rxvt
            my $slave = $pty->slave;

 RESOURCES (available also as long-options)
     Note: `rxvt --help' gives a list of all resources (long options)
     compiled into your version.
-    There are two different methods that rxvt can use to get the Xresource

+        characters will be created (if the resource exists, otherwise, no
+        regex will be created). In this mode, characters outside ISO-8859-1
+        can be used.
+        When the selection extension is not used, only ISO-8859-1 characters

     insecure: *boolean*
         Enables "insecure" mode. Rxvt-unicode offers some escape sequences
         that echo arbitrary strings like the icon name or the locale. This
         could be abused if somebody gets 8-bit-clean access to your display,

         Turn on/off hold window after exit support. If enabled, rxvt will
         not immediately destroy its window when the program executed within

         the user.
         *string* may contain escape values ("\a": bell, "\b": backspace,
         "\e", "\E": escape, "\n": newline, "\r": carriage return, "\t": tab,

         Its usage can be demonstrated by an example:
           URxvt.keysym.M-C-0x61:    list|\033<M-C-|abc|>
         is interpreted and executed as rxvt's control sequence. For example
         the following means "change the current locale to "zh_CN.GBK" when
         Control-Meta-c is being pressed":
           URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
+        If *string* takes the form "perl:STRING", then the specified STRING
+        is passed to the "on_keyboard_command" perl handler. See the
+        rxvtperl(3) manpage. For example, the selection extension (activated
+        via "rxvt -pe selection") listens for "selection:rot13" events:
+          URxvt.keysym.M-C-c: perl:selection:rot13
         Due the the large number of modifier combinations, a defined key
         mapping will match if at *at least* the specified identifiers are
         being set, and no other key mappings with those and more bits are

+        Comma-separated list(s) of perl extension scripts (default:
+        "default") to use in this terminal instance; option -pe.
+        Extension names can be prefixed with a "-" sign to prohibit using
+        them. This can be useful to selectively disable some extensions
+        loaded by default, or specified via the "perl-ext-common" resource.
+        For example, "default,-selection" will use all the default extension
+        except "selection".
+        Extension names can also be followed by an argument in angle
+        brackets (e.g. "searchable-scrollback<M-s>", which binds the hotkey
+        for searchable scrollback to Alt/Meta-s). Mentioning the same
+        extension multiple times with different arguments will pass multiple
+        arguments to the extension.
+        Each extension is looked up in the library directories, loaded if
+        necessary, and bound to the current terminal instance.
+        If both of these resources are the empty string, then the perl
+        interpreter will not be initialized. The idea behind two options is
+        that perl-ext-common will be used for extensions that should be
+        available to all instances, while perl-ext is used for specific
+        instances.

+        Specifies the program to be started with a URL argument. Used by the

 THE SCROLLBAR
     Lines of text that scroll off the top of the rxvt window (resource:
     saveLines) and can be scrolled back using the scrollbar or by
     keystrokes. The normal rxvt scrollbar has arrows and its behaviour is
     fairly intuitive. The xterm-scrollbar is without arrows and its
     disabled -- on the assumption that we are using a fullscreen
     application. Instead, pressing Button1 and Button3 sends ESC [ 6 ~
     (Next) and ESC [ 5 ~ (Prior), respectively. Similarly, clicking on the
     up and down arrows sends ESC [ A (Up) and ESC [ B (Down), respectively.

 CHANGING FONTS

         might have been to enter a reverse tab (Shift-Tab).
     setgid to root or to some other group on others.
 COLORS AND GRAPHICS
     In addition to the default foreground and background colours, rxvt can
     display up to 16 colours (8 ANSI colours plus high-intensity bold/blink
-    versions of the same). Here is a list of the colours with their rgb.txt
+    versions of the same). Here is a list of the colours with their names.
-    names.
        color0          (black)         = Black
        color1          (red)           = Red3
        color2          (green)         = Green3
        color3          (yellow)        = Yellow3
     It is also possible to specify the colour values of foreground,
     background, cursorColor, cursorColor2, colorBD, colorUL as a number
     0-15, as a convenient shorthand to reference the colour name of
     color0-color15.
+    In addition to the colours defined above, rxvt offers an additional 72
+    colours. The first 64 of those (with indices 16 to 79) consist of a
+    4*4*4 RGB colour cube (i.e. *index = r * 16 + g * 4 + b + 16*), followed
+    by 8 additional shades of gray (with indices 80 to 87).
+    Together, all those colours implement the 88 colour xterm colours. Only
+    the first 16 can be changed using resources currently, the rest can only
+    be changed via command sequences ("escape codes").
     Note that -rv ("reverseVideo: True") simulates reverse video by always
     swapping the foreground/background colours. This is in contrast to
     *xterm*(1) where the colours are only swapped if they have not otherwise
     been specified. For example,
     rxvt -fg Black -bg White -rv
         would yield White on Black, while on *xterm*(1) it would yield Black
         on White.
+  ALPHA CHANNEL SUPPORT
+    If Xft support has been compiled in and as long as Xft/Xrender/X don't
+    get their act together, rxvt-unicode will support
+    "rgba:rrrr/gggg/bbbb/aaaa" (recommended, but MUST have 4
+    digits/component) colour specifications, in addition to the ones
+    provided by X, where the additional A component specifies opacity
+    (alpha) values. The minimum value of 0 is completely transparent). You
+    can also prefix any color with "[percent]", where "percent" is a decimal
+    percentage (0-100) that specifies the opacity of the color, where 0 is
+    completely transparent and 100 is completelxy opaque.
+    You probably need to specify "-depth 32", too, and have the luck that
+    your X-server uses ARGB pixel layout, as X is far from just supporting
+    ARGB visuals out of the box, and rxvt-unicode just fudges around.
+    For example, the following selects an almost completely transparent red
+    background, and an almost opaque pink foreground:
+       rxvt -depth 32 -bg rgba:0000/0000/0000/aaaa -fg "[80]pink"
+    *Please note that transparency of any kind if completely unsupported by
+    the author. Don't bug him with installation questions!*
