 .SH DESCRIPTION
 .B st
 is a simple terminal emulator.
@ -72,100 +45,28 @@ for further details.
 .B \-i
 will fixate the position given with the -g option.
 .TP
-.BI \-n " name"
-defines the window instance name (default $TERM).
-.TP
-.BI \-o " iofile"
+.BI \-o " file"
 writes all the I/O to
-.I iofile.
+.I file.
 This feature is useful when recording st sessions. A value of "-" means
 standard output.
 .TP
-.BI \-T " title"
-defines the window title (default 'st').
-.TP
 .BI \-t " title"
 defines the window title (default 'st').
 .TP
 .BI \-w " windowid"
-embeds st within the window identified by
+embeds st within the window identified by 
 .I windowid
 .TP
-.BI \-l " line"
-use a tty
-.I line
-instead of a pseudo terminal.
-.I line
-should be a (pseudo-)serial device (e.g. /dev/ttyS0 on Linux for serial port
-0).
-When this flag is given
-remaining arguments are used as flags for
-.BR stty(1).
-By default st initializes the serial line to 8 bits, no parity, 1 stop bit
-and a 38400 baud rate. The speed is set by appending it as last argument
-(e.g. 'st -l /dev/ttyS0 115200'). Arguments before the last one are
-.BR stty(1)
-flags. If you want to set odd parity on 115200 baud use for example 'st -l
-/dev/ttyS0 parenb parodd 115200'. Set the number of bits by using for
-example 'st -l /dev/ttyS0 cs7 115200'. See
-.BR stty(1)
-for more arguments and cases.
-.TP
 .B \-v
 prints version information to stderr, then exits.
 .TP
-.BI \-e " command " [ " arguments " "... ]"
+.BI \-e " program " [ " arguments " "... ]"
 st executes
-.I command
+.I program
 instead of the shell.  If this is used it
 .B must be the last option
 on the command line, as in xterm / rxvt.
-This option is only intended for compability,
-and all the remaining arguments are used as a command
-even without it.
-.SH SHORTCUTS
-.TP
-.B Break
-Send a break in the serial line.
-Break key is obtained in PC keyboards
-pressing at the same time control and pause.
-.TP
-.B Ctrl-Print Screen
-Toggle if st should print to the
-.I iofile.
-.TP
-.B Shift-Print Screen
-Print the full screen to the
-.I iofile.
-.TP
-.B Print Screen
-Print the selection to the
-.I iofile.
-.TP
-.B Alt-Shift-Page Up
-Increase font size.
-.TP
-.B Alt-Shift-Page Down
-Decrease font size.
-.TP
-.B Alt-Shift-Home
-Reset to default font size.
-.TP
-.B Shift-Insert
-Paste from primary selection (middle mouse button).
-.TP
-.B Alt-Shift-Insert
-Paste from clipboard selection.
-.TP
-.B Alt-Shift-c
-Copy the selected text to the clipboard selection.
-.TP
-.B Alt-Shift-v
-Paste from the clipboard selection.
-.TP
-.B Alt-Ctrl
-Launch dmenu to enter a unicode codepoint and send the corresponding glyph

Roberto E. Vargas Caballero	e8f1308586	Receive only a wchar_t in tchar() It makes simpler the conversion from utf8 input string and makes simpler the checks done in tputc, but it still requires a lot of additional conversions that will be removed later.	2014-09-26 19:25:07 +02:00
Roberto E. Vargas Caballero	d65ebe9aed	First step to plain unicode representation tprinter() is used in tputc, so a first step is to change it to accept a wchar_t instead of a multibyte string. This patch makes more ugly the code because it needs a lot of conversions, but they will be removed later.	2014-09-26 19:25:07 +02:00
Roberto E. Vargas Caballero	28f56c8842	Remove last parameter of utf8encode This parameter was always UTF_SIZ, so it is better remove it and use directly UTF_SIZ in in.	2014-09-26 19:25:06 +02:00
