v07i055: keydef - quickly, easily redefine VT[23]xx function keys
This is my turn.
My keydef program makes the VT[23]xx (and compatibles) key definition
in a different way than the Brandon's. [Huh? I just moderate. ++bsa]
I have NOT encountered the problems that he declared (half of the keys
are not programmable, errors in downloading long definitions, etc.).
This keydef can define the entire set of the user-defined keys; more,
it can clean all the keys, and/or lock all them.
Not X/OPEN (or SysV) users will need to edit one line in keydef.c to
change the #include <string.h> to #include <strings.h>. I don't know
if other changes are requested for the sites that are not X/OPEN.
My English is very bad, but I hope that you will read the manual page,
at least to see all the features.

X.TH KEYDEF local
X.SH NAME
Xkeydef - quickly / easily redefines VT2xx and VT3xx function keys.
X.SH SYNTAX
Xkeydef { [-c] [-l] [keyname1 keyname2 ...] }
X.br
Xkeydef [-f filename [keyname1 keyname2 ...]]
X.SH DESCRIPTION
XThe first sintax specification for the \fIkeydef\fP command is
Xinteractive; at least one flag or a keyname must be specified. For
Xeach \fIkeyname\fP, \fIkeydef\fP asks for its definition. The \fB-c\fP
Xand \fB-l\fP flags have the same meaning, respectively, of
Xthe \fIclear\fP and \fIlock\fP commands used in non-interactive mode
X(see below). Definition follows the same sintax used not interactively.
X.PP
XUsing the 2nd form, \fIkeydef\fP reads its instructions
Xfrom \fIfilename\fP; if \fIfilename\fP is "\fB-\fP", commands are taken
Xfrom standard input, else if it is missing ("\fIkeydef\fP" with no
Xarguments specified), then \fI$HOME/.keydef\fP is read.
X.PP
XCommands in \fIfilename\fP are specified in a shell-like sintax.
XA command is a sequence of non-blank words separated by blanks (a blank
Xis a tab or a space). The first word specifies the name of the command
Xto be executed. Possible commands are \fIclear\fP (to clear all the
Xdefinitions previously set), \fIlock\fP (to lock definitions: i.e.,
Xall the User Defined Keys will be locked after the execution
Xof \fIkeydef\fP -- keys unlock is possible only via Set-Up),
Xor \fIkeyname\fP (to set a definition for \fIkeyname\fP function-key);
X\fIkeyname\fP must be a valid name of a function key, and a
X\fIdefinition\fP follows it.
X.PP
XA word beginning with \fB#\fP causes that word and all the following
Xcharacters up to a new line to be ignored. Explicit null arguments
X(\fB""\fP or \fB''\fP) are retained. A character may be quoted (i.e.,
Xmade to stand for itself) by preceding it with a \fB\\\fP. The
Xpair \fB\\newline\fP is ignored. All characters enclosed between a pair
Xof quote marks (\fB''\fP or \fB""\fP), except the mark itself, are
Xquoted; inside them, \fB\\\fP has no quoting properties.
X.PP
XValid \fIkeynames\fP are \fBF6\fP to \fBF20\f, and \fBS6\fP to \fBS20\fP
X(referenced pressing both the \fBShift\fP and the function key). Some
Xkeys are also referenced by the associated name (ESC, BS, LF, Help, Do).
XType "\fIkeydef -\fP" to print the list of all the possible keynames.
X.PP
XThe (mandatory) argument of a \fIkeyname\fP command is the
X\fIdefinition\fP for that key; inside it, \fB\\\fP and \fB^\fP have a
Xspecial meaning. Certain characters may be represented according to the
Xfollowing table:
X.nf
X
X CHARACTER ASCII SYMBOL ESCAPE SEQUENCE
X
X newline(NL) LF \\n
X horizontal-tab HT \\t
X vertical-tab VT \\v
X backspace BS \\b
X carriage-return CR \\r
X formfeed FF \\f
X escape ESC \\e
X backslah \\ \\\\
X single-quote ' \\' or \\Q
X double-quote " \\D
X bit-pattern ddd \\ddd
X
X.fi
XThe escape \fB\\ddd\fP consists of the backslash followed by 1, 2, or 3
Xoctal digits, which are taken to specify the value of the desired
Xcharacter. If the character following a backslash is not one of those
Xspecified, the backslash is ignored. \fB^x\fP maps to a control-x for
Xany appropriate x. To program a literal circumflex, preceed it with a
Xbackslash.
X.PP
XA function key is executed by pressing one of the function keys
X(\fBF*\fP), or by pressing SHIFT + function key (\fBS*\fP).
X.SH WARNINGS
XThere is a finite amount of memory in the terminal for storing the
Xdefinitions. The exceeding characters are discharged.
X.PP
XTerminal is getting confused when any character is asynchronously
Xreceived/typed during the execution of \fIkeydef\fP.
X.PP
XDepending on the terminal type and/or setting, not all the keys
Xcan be programmed; typically, F11 (ESC), F12 (BS) and F13 (LF)
Xcan be protected from the user's redefinition.
X.PP
XThis program has been developed and tested on an \fIOlivetti WS 685\fP
Xdesktop video display terminal emulating DEC terminals VT220, VT100 and
XVT52, connected via RS232 to an \fIOlivetti LSX-3010\fP with the \fIL2
XX/OS R2.0\fP Unix System. You should not have porting problems on any
XX/OPEN system.

X The first sintax specification for the _k_e_y_d_e_f command is
X interactive; at least one flag or a keyname must be
X specified. For each _k_e_y_n_a_m_e, _k_e_y_d_e_f asks for its definition.
X The ----cccc and ----llll flags have the same meaning, respectively, of
X the _c_l_e_a_r and _l_o_c_k commands used in non-interactive mode
X (see below). Definition follows the same sintax used not
X interactively.
X
X Using the 2nd form, _k_e_y_d_e_f reads its instructions from
X _f_i_l_e_n_a_m_e; if _f_i_l_e_n_a_m_e is "----", commands are taken from
X standard input, else if it is missing ("_k_e_y_d_e_f" with no
X arguments specified), then $_H_O_M_E/._k_e_y_d_e_f is read.
X
X Commands in _f_i_l_e_n_a_m_e are specified in a shell-like sintax.
X A command is a sequence of non-blank words separated by
X blanks (a blank is a tab or a space). The first word
X specifies the name of the command to be executed. Possible
X commands are _c_l_e_a_r (to clear all the definitions previously
X set), _l_o_c_k (to lock definitions: i.e., all the User Defined
X Keys will be locked after the execution of _k_e_y_d_e_f -- keys
X unlock is possible only via Set-Up), or _k_e_y_n_a_m_e (to set a
X definition for _k_e_y_n_a_m_e function-key); _k_e_y_n_a_m_e must be a
X valid name of a function key, and a _d_e_f_i_n_i_t_i_o_n follows it.
X
X A word beginning with #### causes that word and all the
X following characters up to a new line to be ignored.
X Explicit null arguments ("""""""" or '''''''') are retained. A character
X may be quoted (i.e., made to stand for itself) by preceding
X it with a \\\\. The pair \\\\nnnneeeewwwwlllliiiinnnneeee is ignored. All characters
X enclosed between a pair of quote marks ('''''''' or """"""""), except
X the mark itself, are quoted; inside them, \\\\ has no quoting
X properties.
X
X Valid _k_e_y_n_a_m_e_s are FFFF6666 to FFFF22220000 aaaannnndddd SSSS6666 ttttoooo SSSS22220000 ((((rrrreeeeffffeeeerrrreeeennnncccceeeedddd

X the desired character. If the character following a
X backslash is not one of those specified, the backslash is
X ignored. ^^^^xxxx maps to a control-x for any appropriate x. To
X program a literal circumflex, preceed it with a backslash.
X
X A function key is executed by pressing one of the function
X keys (FFFF****), or by pressing SHIFT + function key (SSSS****).

X There is a finite amount of memory in the terminal for
X storing the definitions. The exceeding characters are
X discharged.
X
X Terminal is getting confused when any character is
X asynchronously received/typed during the execution of
X _k_e_y_d_e_f.
X
X Depending on the terminal type and/or setting, not all the
X keys can be programmed; typically, F11 (ESC), F12 (BS) and
X F13 (LF) can be protected from the user's redefinition.
