1726 uses that as the name of the system-wide lesskey file.
1729 looks in a standard place for the system-wide lesskey file:
1730 On Unix systems, the system-wide lesskey file is /usr/local/etc/syslesskey.
1735 On MS-DOS and Windows systems, the system-wide lesskey file is c:\e_syslesskey.
1736 On OS/2 systems, the system-wide lesskey file is c:\esyslesskey.ini.

2353 If the \-m option is not set, the medium prompt is used,
2354 and it is prefixed with the string "\-\-More\-\-".
2355 If the \-m option is set, the short prompt is used.
