Find and replace
Sometimes an interface or solution you describe changes, and you need to rename some feature, field, or button through the whole help instance.
You can search for a specific string within a project, apply scopes to limit the search area, and exclude items from the search using Find in Files function.
Find the string usages in the project
From the main menu, selector press Ctrl+Shift+F
Type what you search for.
To limit the scope on the Scope tab, in the list select either Only topics included in the current product, Only topics not included in the current product, or Only topics included in the current product and libraries.
Replace the string usages in a project
In the editor, highlight the string you want to find and replace.
Press Ctrl+Shift+R to open the Replace in Path dialog. The highlighted line will appear in the top field.
In the bottom field, type what you want to replace it for.
Click the Replace button to make replacements one by one, or Replace all to replace all found items.
To exclude some items, click an icon with two A letters located in the bottom field.
