This dialog is displayed when you select the Find in Files… option from the Edit menu of the Code window. It provides you with the facility to search across multiple files for a specified string. You can limit the search by specifying how the string is used in the code.
Make sure that you save any files that
you are editing before starting the search.

Move the mouse pointer across the picture
and click where you want to see a description.
The results of the search are displayed
in the FileFind
tab of the Code window Output
pane as an entry for each matching line of code. The first file
in the list is displayed on a corresponding tab in the Code
window File Editor pane, with
a pointer to the first matched source line. Double-click
on the entries in the FileFind
tab to move through the list, or select Find
Next from the Edit menu.
