Reading the Supercard manual #2

[Richmond Mathewson]

  "Using Help From Within the Script Editor
The Help System's Language Guide entries can be looked up automatically 
from within SuperCard's or
SuperEdit's script editor window. Simply hilite the word you wish to 
lookup and press Command-?. If the
help system is currently not running it will be launched and the 
Language Guide window will open to
the hilited entry. If the highlighted word is not a SuperTalk word the 
help system will tell you."
