A Find & Replace function has been added to the Text tool. This performs live search so that as you type the search string the text is searched and highlighted in real-time.
To search for some text select the menu Edit -> Find/Replace or Ctrl+Alt+F and the following dialog is displayed.
Enter the search string and it's shown highlighted in the text. You can choose to search just the current text story, page or the whole document (all text flows on all pages).
The 'whole word' option will only search for whole words that match the search string. E.G. searching for 'met' will not find 'metro'. The 'Case sensitive' option will match only the exact case. E.G. with this option on, searching for 'aBc' will not find 'abc'.
