=head1 NAME

rxvt-unicode (ouR XVT, unicode) - (a VT102 emulator for the X window system)

=head1 SYNOPSIS

B<@@RXVT_NAME@@> [options] [-e command [ args ]]

=head1 DESCRIPTION

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

See also @@RXVT_NAME@@(7) for technical reference documentation (escape
sequences etc.).

=head1 OPTIONS

The B<@@RXVT_NAME@@> options (mostly a subset of I<xterm>'s) are listed
below. In keeping with the smaller-is-better philosophy, options may be
eliminated or default values chosen at compile-time, so options and
defaults listed may not accurately reflect the version installed on
your system. `rxvt -h' gives a list of major compile-time options on
the I<Options> line. Option descriptions may be prefixed with which
compile option each is dependent upon. e.g. `Compile I<XIM>:' requires
I<XIM> on the I<Options> line. Note: `rxvt -help' gives a list of all
command-line options compiled into your version.

Note that B<@@RXVT_NAME@@> permits the resource name to be used as a
long-option (--/++ option) so the potential command-line options are
far greater than those listed. For example: `rxvt --loginShell --color1
Orange'.

The following options are available:

=head1 RESOURCES (available also as long-options)

Note: `@@RXVT_NAME@@ --help' gives a list of all resources (long
options) compiled into your version.

There are two different methods that @@RXVT_NAME@@ can use to get the
Xresource data: using the X libraries (Xrm*-functions) or internal
Xresources reader (B<~/.Xdefaults>). For the first method (ie.
B<@@RXVT_NAME@@ -h> lists B<XGetDefaults>), you can set and change the
resources using X11 tools like B<xset>. Many distribution do also load
settings from the B<~/.Xresources> file when X starts.

If compiled with internal Xresources support (i.e. B<@@RXVT_NAME@@ -h>
lists B<.Xdefaults>) then B<@@RXVT_NAME@@> accepts application defaults
set in XAPPLOADDIR/URxvt (compile-time defined: usually
B</usr/lib/X11/app-defaults/URxvt>) and resources set in
B<~/.Xdefaults>, or B<~/.Xresources> if B<~/.Xdefaults> does not exist.
Note that when reading X resources, B<@@RXVT_NAME@@> recognizes two
class names: B<XTerm> and B<URxvt>. The class name B<Rxvt> allows
resources common to both B<@@RXVT_NAME@@> and the original I<rxvt> to be
easily configured, while the class name B<URxvt> allows resources
unique to B<@@RXVT_NAME@@>, notably colours and key-handling, to be
shared between different B<@@RXVT_NAME@@> configurations. If no
resources are specified, suitable defaults will be used. Command-line
arguments can be used to override resource settings. The following
resources are allowed:

=over 4

=item B<geometry:> I<geom>

Create the window with the specified X window geometry [default 80x24];
option B<-geometry>.

colours. The canonical names are as follows: 0=black, 1=red, 2=green,
3=yellow, 4=blue, 5=magenta, 6=cyan, 7=white, but the actual colour
names used are listed in the B<COLORS AND GRAPHICS> section.

extension to be able to input japanese characters while staying in
another locale. option B<-imlocale>.

=item B<insecure>

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, wether
throuh a mail client displaying mail bodies unfiltered or though
write(1). Therefore, these sequences are disabled by default. (Note
that other terminals, including xterm, have these sequences
enabled by default). You can enable them by setting this boolean
resource or specifying B<-insecure> as an option. At the moment, this
enabled display-answer, locale, findfont, icon label and window title
requests as well as dynamic menubar dispatch.

=item B<modifier:> I<modifier>

Set the key to be interpreted as the Meta key to: B<alt>, B<meta>,
B<hyper>, B<super>, B<mod1>, B<mod2>, B<mod3>, B<mod4>, B<mod5>; option
B<-mod>.

=item B<answerbackString:> I<string>

Specify the reply rxvt sends to the shell when an ENQ (control-E)
character is passed through. It may contain escape values as described
in the entry on B<keysym> following.

=item B<secondaryScreen:> I<bool>

Turn on/off secondary screen (default enabled).

=item B<secondaryScroll:> I<bool>

Turn on/off secondary screen scroll (default enabled). If the this
option is enabled, scrolls on the secondary screen will change the
scrollback buffer and switching to/from the secondary screen will
instead scroll the screen up.

=item B<keysym.>I<sym>: I<string>

Associate I<string> with keysym I<sym> (B<0xFF00 - 0xFFFF>). It may
contain escape values (\a: bell, \b: backspace, \e, \E: escape, \n:
newline, \r: return, \t:
tab, \000: octal number) or control characters (^?: delete, ^@: null,
^A ...) and may enclosed with double quotes so that it can start or end
with whitespace. The intervening resource name B<keysym.> cannot be
omitted. This resource is only available when compiled with
KEYSYM_RESOURCE.

=back

=head1 THE SCROLLBAR

Lines of text that scroll off the top of the B<@@RXVT_NAME@@> window
(resource: B<saveLines>) and can be scrolled back using the scrollbar
or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
arrows and its behaviour mimics that of I<xterm>

Scroll down with B<Button1> (B<xterm-scrollbar>) or B<Shift-Next>.
Scroll up with B<Button3> (B<xterm-scrollbar>) or B<Shift-Prior>.
Continuous scroll with B<Button2>.

=head1 MOUSE REPORTING

To temporarily override mouse reporting, for either the scrollbar or
the normal text selection/insertion, hold either the Shift or the Meta
(Alt) key while performing the desired mouse action.

If mouse reporting mode is active, the normal scrollbar actions are
disabled -- on the assumption that we are using a fullscreen
application. Instead, pressing Button1 and Button3 sends B<ESC[6~>
(Next) and B<ESC[5~> (Prior), respectively. Similarly, clicking on the
up and down arrows sends B<ESC[A> (Up) and B<ESC[B> (Down),
respectively.

=head1 TEXT SELECTION AND INSERTION

The behaviour of text selection and insertion mechanism is similar to
I<xterm>(1).

=over 4

=item B<Selection>:

Left click at the beginning of the region, drag to the end of the
region and release; Right click to extend the marked region; Left
double-click to select a word; Left triple-click to select the entire
line.

=item B<Insertion>:

Pressing and releasing the Middle mouse button (or B<Shift-Insert>) in
an B<@@RXVT_NAME@@> window causes the current text selection to be
inserted as if it had been typed on the keyboard.

=back

=head1 CHANGING FONTS

You can change fonts on-the-fly, which is to say cycle through the
default font and others of various sizes, by using B<Shift-KP_Add> and
B<Shift-KP_Subtract>. Or, alternatively (if enabled) with
B<@@HOTKEY@@-@@BIGFONT@@> and B<@@HOTKEY@@-@@SMALLFONT@@>, where the
actual key can be selected using resources
B<smallfont_key>/B<bigfont_key>.

=head1 ISO 14755 SUPPORT

Partial ISO 14755-support is implemented. that means that pressing

Section 5.1: Control and Shift together enters unicode input
mode. Entering hex digits composes a Unicode character, pressing space or
releasing the modifiers commits the keycode and every other key cancels
the current input character.

Section 5.2: Pressing and immediately releasing Control and Shift together
enters keycap entry mode for the next key: pressing a function key (tab,
return etc..) will enter the unicode character corresponding to the given
key.

=head1 LOGIN STAMP

B<@@RXVT_NAME@@> tries to write an entry into the I<utmp>(5) file so
that it can be seen via the I<who(1)> command, and can accept messages.
To allow this feature, B<@@RXVT_NAME@@> must be installed setuid root on
some systems.

=head1 COLORS AND GRAPHICS

In addition to the default foreground and background colours,
B<@@RXVT_NAME@@> 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 B<rgb.txt> names.

=begin table

        B<color0>       (black) = Black

It is also possible to specify the colour values of B<foreground>,
B<background>, B<cursorColor>, B<cursorColor2>, B<colorBD>, B<colorUL> as
a number 0-15, as a convenient shorthand to reference the colour name of
color0-color15.

Note that B<-rv> (B<"reverseVideo: True">) simulates reverse video by
always swapping the foreground/background colours. This is in contrast to
I<xterm>(1) where the colours are only swapped if they have not otherwise
been specified. For example,

=over 4

=item B<rxvt -fg Black -bg White -rv>

would yield White on Black, while on I<xterm>(1) it would yield Black
on White.

=head1 ENVIRONMENT

B<@@RXVT_NAME@@> sets the environment variables B<TERM>, B<COLORTERM>
and B<COLORFGBG>. The environment variable B<WINDOWID> is set to the X
window id number of the B<@@RXVT_NAME@@> window and it also uses and
sets the environment variable B<DISPLAY> to specify which display
terminal to use. B<@@RXVT_NAME@@> uses the environment variables
B<RXVTPATH> and B<PATH> to find XPM files.
