To find a string of text in a script (no matter where it's located), type
the following into the message box:
ss "search string "
For example, in order to find a handler called MoveItAround, type
ss "MoveItAround"
into the message box. HyperCard will search all scripts in the open stack.
When it finds the script containing the string, it will stop and open the
script up. To find exactly where the string is within the script, choose
"Find" under the "Go" menu or type command-F. HyperCard will have
automatically copied and pasted the string into the Find window. At this
point, hitting the Enter key will find it and show you exactly where it is
in the script.
