1741 A system-wide lesskey source file may also be set up to provide key bindings.
1743 system-wide file, key bindings in the local file take precedence over
1744 those in the system-wide file.
1747 uses that as the name of the system-wide lesskey file.
1750 looks in a standard place for the system-wide lesskey file:
1751 On Unix systems, the system-wide lesskey file is /usr/local/etc/syslesskey.
1756 On MS-DOS and Windows systems, the system-wide lesskey file is c:\e_syslesskey.
1757 On OS/2 systems, the system-wide lesskey file is c:\esyslesskey.ini.

1983 Selects the UTF-8 encoding of the ISO 10646 character set.
1984 UTF-8 is special in that it supports multi-byte characters in the input file.
1985 It is the only character set that supports multi-byte characters.

2130 The \-P option allows you to tailor the prompt to your preference.
2131 The string given to the \-P option replaces the specified prompt string.
2150 and a "j" means use the "target" line, as specified by the \-j option.

2327 In this mode, these features are disabled:
2339 use of lesskey files (-k and \-\-lesskey-src)

2355 use of tags files (-t)
2357 The LESSSECURE_ALLOW environment variable can be set to a comma-separated list
2360 A feature name may be abbreviated as long as the abbreviation is unambiguous.
2372 Less can also be compiled to be permanently in "secure" mode.
2383 In this mode, less behaves differently in these ways:
2385 The \-e option works differently.
2386 If the \-e option is not set,
2388 behaves as if the \-e option were set.
2389 If the \-e option is set,
2391 behaves as if the \-E option were set.
2393 The \-m option works differently.
2394 If the \-m option is not set, the medium prompt is used,
2395 and it is prefixed with the string "\-\-More\-\-".
2396 If the \-m option is set, the short prompt is used.
2398 The \-n option acts like the \-z option.
2399 The normal behavior of the \-n option is unavailable in this mode.
2401 The parameter to the \-p option is taken to be a
