How about the underscore "_" ? Has something to do with language support I know.

Lee Ambrosius

Hello,

The _ (underscore) is a valid character that can be placed in front of a command name among the . (period). This article really wasn't directly focused on macro customization, but really rather the context of command names themselves. The _ (underscore) character is used for creating menu macros and used with commands in AutoLISP that allow them to be portable between different languages of AutoCAD. I do plan on covering menu customization and these characters at a later date, but primarily the focus was on the commands with and without - (hyphens) or + (pluses) as the commands are defined in AutoCAD.

Sincerely,
Lee
