Here are some scripts that provide at least one possible answer to a common need: finding all of the scripts in a suite that use a particular image name, global variable, command, or function; and possibly changing those occurrences to some other name.
The two scripts in this suite will each search for some text in all of the scripts in a suite, or even across several suites at once. You may use them as is, or adapt them to your particular needs.
The FindInAllScripts script prompts you to select a suite (or several suites), and to enter the text to search for. It then opens every script in the selected suites which contains the search text.
The ReplaceInAllScripts script asks for some replacement text in addition to the search text. It also asks whether you would like to be asked about each script, in order to allow you to select which scripts will be changed. It then replaces every occurrence of the search text with the replacement text in all of the scripts in the selected suites or folders.
[Note to current beta testers: Due to a bug in the answer folder command in 4.1 beta 3, these scripts will terminate prematurely. Use an earlier version instead. This bug has been fixed for the final release of 4.1]
