		22	=head1 RXVT-UNICODE VS. RXVT
		23
		24	Unlike the original rxvt, B<rxvt-unicode> stores all text in Unicode
		25	internally. That means it can store and display most scripts in the
		26	world. Being a terminal emulator, however, some things are very difficult,
		27	especially cursive scripts such as arabic, vertically written scripts
		28	like mongolian or scripts requiring extremely complex combining rules,
		29	like tibetan or devenagari. Don't expect pretty output when using these
		30	scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
		31	fine, though. A somewhat difficult case are left-to-right scripts, such
		32	as hebrew: B<rxvt-unicode> adopts the view that bidirectional algorithms
		33	belong into the application, not the terminal emulator (too many things --
		34	such as cursor-movement while editing -- break otherwise), but that might
		35	change.
		36
		37	If you are looking for a terminal that supports more exotic scripts, let
		38	me recommend C<mlterm>, which is a very userfriendly, lean and clean
		39	terminal emulator. In fact, the reason rxvt-unicode was born was solely
		40	because the author couldn't get C<mlterm> to use one font for latin1 and
		41	another for japanese.
		42
		43	Therefore another design rationale was the use of multiple fonts to
		44	display characters: The idea of a single unicode font which many other
		45	programs force onto it's users never made sense to me: You should be able
		46	to choose any font for any script freely.
		47
		48	Apart from that, rxvt-unicode is also much better internationalised than
		49	it's predecessor, supports things such as XFT and ISO 14755 that are handy
		50	in i18n-environments, is faster, and has a lot less bugs than the original
		51	rxvt. This all in addition to dozens of other small improvements.
		52
		53	It is still faithfully following the original rxvt idea of being lean
		54	and nice on resources: for example, you can still configure rxvt-unicode
		55	without most of it's features to get a lean binary. It also comes with
		56	a client/daemon pair that lets you open any number of terminal windows
		57	from within a single process, which makes startup time very fast and
		58	drastically reduces memory usage. See @@RXVT_NAME@@d(1) (daemon) and
		59	@@RXVT_NAME@@c(1) (client).
		60
		61	It also makes technical information about escape sequences (which have
		62	been extended) easier accessible: see @@RXVT_NAME@@(7) for technical
		63	reference documentation (escape sequences etc.).

		890	one.
		891
		892	As an example of use, imagine a business card with a japanese e-mail
		893	address, which you cannot type. Fortunately, the card has the e-mail
		894	address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
		895	by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
		896	followed by releasing the modifier keys.
		897
		898	=item 5.2: Keyboard symbols entry method
		899
		900	This mode lets you input characters representing the keycap symbols of
		901	your keyboard, if representable in the current locale encoding.
		902
		903	Start by pressing C<Control> and C<Shift> together, then releasing
		904	them. The next special key (cursor keys, home etc.) you enter will not
		905	invoke it's usual function but instead will insert the corresponding
		906	keycap symbol. The symbol will only be entered when the key has been
		907	released, otherwise pressing e.g. C<Shift> would enter the symbol for
		908	C<ISO Level 2 Switch>, although your intention might have been to enter a
		909	reverse tab (Shift-Tab).
		910
		911	=item 5.3: Screen-selection entry method
		912
		913	While this is implemented already (it's basically the selection
		914	mechanism), it could be extended by displaying a unicode character map.
		915
		916	=item 5.4: Feedback method for identifying displayed characters for later input
		917
		918	This method lets you display the unicode character code associated with
		919	characters already displayed.
		920
		921	You enter this mode by holding down C<Control> and C<Shift> together, then
		922	pressing and holding the left mouse button and moving around. The unicode
		923	hex code(s) (it might be a combining character) of the character under the
		924	pointer is displayed until you release C<Control> and C<Shift>.
		925
		926	In addition to the hex codes it will display the font used to draw this
		927	character - due to implementation reasons, characters combined with
		928	combining characters, line drawing characters and unknown characters will
		929	always be drawn using the built-in support font.

862	=item How do I know which rxvt-unicode version I'm using?
863
864	The version number is displayed with the usage (-h). For rxvt-unicode
865	version 2.14 and later, the escape sequence C<ESC[8n> sets the window
866	title to the version number.
867
868	=item Mouse cut/paste suddenly no longer works.
869
870	Make sure that mouse reporting is actually turned off since killing
871	some editors prematurely may leave the mouse in mouse report mode. I've
872	heard that tcsh may use mouse reporting unless it otherwise specified. A
873	quick check is to see if cut/paste works when the Alt or Shift keys are
874	depressed. See @@RXVT_NAME@@(7)
875
876	=item What's with this bold/blink stuff?
877
878	If no bold colour is set via C<colorBD:>, bold will invert text using the
879	standard foreground colour.
880
881	For the standard background colour, blinking will actually make the
882	text blink when compiled with C<--enable-blinking>. with standard
883	colours. Without C<--enable-blinking>, the blink attribute will be
884	ignored.
885
886	On ANSI colours, bold/blink attributes are used to set high-intensity
887	foreground/background colors.
888
889	color0-7 are the low-intensity colors.
890
891	color8-15 are the corresponding high-intensity colors.
892
893	=item I don't like the screen colors. How do I change them?
894
895	You can change the screen colors at run-time using F<~/.Xdefaults>
896	resources (or as long-options).
897
898	Here are values that are supposed to resemble a VGA screen,
899	including the murky brown that passes for low-intensity yellow:
900
901	Rxvt*color0: #000000
902	Rxvt*color1: #A80000
903	Rxvt*color2: #00A800

916	Rxvt*color14: #00FFFF
917	Rxvt*color15: #FFFFFF
918
919	=item What's with the strange Backspace/Delete key behaviour?
920
921	Assuming that the physical Backspace key corresponds to the
922	BackSpace keysym (not likely for Linux ... see the following
923	question) there are two standard values that can be used for
924	Backspace: C<^H> and C<^?>.
925
926	Historically, either value is correct, but rxvt-unicode adopts the debian
927	policy of using C<^?> when unsure, because it's the one only only correct
928	choice :).
929
930	Rxvt-unicode tries to inherit the current stty settings and uses the value
931	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
932	started from a terminal (say, from a menu or by remote shell), then the
933	system value of `erase', which corresponds to CERASE in <termios.h>, will
934	be used (which may not be the same as your stty setting).
935
936	For starting a new rxvt-unicode:
937
938	# use Backspace = ^H
939	$ stty erase ^H
940	$ @@RXVT_NAME@@
941
942	# use Backspace = ^?
943	$ stty erase ^?
944	$ @@RXVT_NAME@@
945
946	Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
947
948	For an existing rxvt-unicode:
949
950	# use Backspace = ^H
951	$ stty erase ^H
952	$ echo -n "^[[36h"
953
954	# use Backspace = ^?
955	$ stty erase ^?
956	$ echo -n "^[[36l"
957
958	This helps satisfy some of the Backspace discrepancies that occur, but
959	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
960	properly reflects that.
961
962	The Delete key is a another casualty of the ill-defined Backspace problem.
963	To avoid confusion between the Backspace and Delete keys, the Delete
964	key has been assigned an escape sequence to match the vt100 for Execute
965	(ESC[3~) and is in the supplied termcap/terminfo.
966
967	Some other Backspace problems:
968
969	some editors use termcap/terminfo,
970	some editors (vim I'm told) expect Backspace = ^H,
971	GNU Emacs (and Emacs-like editors) use ^H for help.
972
973	Perhaps someday this will all be resolved in a consistent manner.
974
975	=item I don't like the key-bindings. How do I change them?
976
977	There are some compile-time selections available via configure. Unless
978	you have run "configure" with the C<--disable-resources> option you can
979	use the `keysym' resource to alter the keystrings associated with keysym
980	0xFF00 - 0xFFFF (function, cursor keys, etc).
981
982	Here's an example for a tn3270 session started using `@@RXVT_NAME@@ -name tn3270'
983
984	!# ----- special uses ------:
985	! tn3270 login, remap function and arrow keys.

1023	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
1024	How do I make use of them? For example, the Sun Keyboard type 4
1025	has the following mappings that rxvt-unicode doesn't recognize.
1026
1027	KP_Insert == Insert
1028	F22 == Print
1029	F27 == Home
1030	F29 == Prior
1031	F33 == End
1032	F35 == Next
1033
1034	Rather than have rxvt-unicode try to accomodate all the various possible keyboard
1035	mappings, it is better to use `xmodmap' to remap the keys as required for
1036	your particular machine.
1037
1038	=item How do I distinguish if I'm running rxvt-unicode or a regular xterm?
1039	I need this to decide about setting colors etc.
1040
1041	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
1042	check and see if that is set. Note that several programs, JED, slrn,
1043	Midnight Commander automatically check this variable to decide whether or
1044	not to use color.
1045
1046	=item How do I set the correct, full IP address for the DISPLAY variable?
1047
1048	If you've compiled rxvt-unicode with DISPLAY_IS_IP and ahve enabled
1049	insecure mode then it is possible to use the following shell script
1050	snippets to correctly set the display. If your version of rxvt-unicode
1051	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1052	the COLORTERM variable can be used to distinguish rxvt-unicode from a
1053	regular xterm.
