vBulletin Manual - Search Templates

When you do not know which template resides in which style, or which template to modify, than use the Styles & Templates > Search in Templates > Search Templates system to find the template in one or more styles.

Search in Style
Select the style in which you want to search. You can select to search in all the styles or just one.
Search for Text
Enter the string of text you want to search for. This search string is case sensitive. The search will find any words / phrases containing the string you enter here. For example, if you search for "bullet" the search will find "vbulletin", "bullets", etc.
Additionally you could select the [Large Edit Box] if you have a chunk of text which you would like to have an overview on while entering.
Search Titles Only
Select yes if you want to search only through the template titles and not through the actual content of the templates.

Note:

Use the Styles & Templates > Search in Templates > Find and Replace in Templates feature if you have a lot of templates in one or more styles that has text that you wish to have replaced. This could save you quite some time.
