To search (and replace) within a script, you’ll use the find bar and the Search menu.

To summon the find bar:

• Choose Search > Find.

To dismiss the find bar:

• Click Done in the find bar.

• Or, press Esc.

To configure a search in the find bar, use the checkboxes:

• RegEx. If checked, the search string (and replace string) will be interpreted as a regular expression. Script Debugger uses the ICU flavor of regular expression syntax.

  By default, . doesn’t match the return character at the end of a line; you can reverse this with the (?s) flag.

• Match Word. If checked, the search string is sought between word boundaries.

• Ignore Case. If checked, the search is case-insensitive.

• Wrap. If checked, successive Find Again commands loop around the document. If unchecked, Replace All affects text only after the start of the current selection.

To perform a search:

• The search is initially performed automatically as you edit the search string.

• To search forward or backward, choose Search > Find Again (Backwards), or click the arrow buttons in the find bar.

  The Wrap checkbox affects the behavior of this command.

To perform a search-and-replace:

• Click the & Replace button to reveal the replace string and Replace buttons.

• Click a Replace button or choose a Replace command from the Search menu.

  The Wrap checkbox affects the behavior of Replace All (and Replace & Find).

You can use selected text as the search or replace term; choose Search > Find Selection (Backwards) or Use Selection for Find/Replace.

To recall a recent search, click the magnifying-glass icon in the search field.

An Editor preference, “Share Find string with other applications,” determines whether the search string is shared with the system-wide Find pasteboard.
