Lexicon of a Document: an Overview
There is an On-line Lexicon of the Mathscript language that can be brought up from any Script Window, or from the Objects Menu. If you are uncertain about the syntax of a command or function, or if you simply want to view the system and user-defined Commands, Programs, or Objects currently known to Mathscript, get the Field menu by right-button mouse click, and you will be given the option to view the lexicon. If you double-click on an entry, the definition will appear. The text of the definition may then be selected and copied to the clipboard.
