Using Find and Replace with User Globals
In order to use the Find and Replace command on User Globals, you must right-click the User icon in the Globals folder in the system tree, and select Find and Replace from the menu. You cannot perform a Find and Replace on User Globals by selecting Find and Replace from the Edit menu (Classic view) or on the Home tab, in the Editing group, click Find and Replace (Ribbon view). That menu belongs to the active document only.
Note that the Find and Replace dialog box displays the name of the document being searched in its title bar. For example, if you perform a Find and Replace on User Globals, Find and Replace User appears in the title bar.
