moreAdditionalHelp
"A replacement for the standard “Additional Help†menu item - allowing any hlp - rtf - doc - .txt - .htm - or pdf file in the Help directory to be opened - in addition to chm files. Very handy for keeping track of various Read Me files - such as those that come with freeware/shareware plug-ins.
The script should run as-is in MAX 4 and above and in MAX 3 with Simon Feltman’s CtrlLib extension."
