PDF Annotator has an easy-to-use search function that points out all occurrences of a search string in the document, and will take you from one to the next.
To perform a search, choose Edit Find, enter the desired expression in the text box and press the ENTER key to start the search or the Down or Up keys to continue searching in either direction. If you stop entering text for a few seconds, the search will also start automatically.
Use the Match Case option to perform a search using the exact case of the text that you are entering.
If the Highlight All setting is selected, PDF Annotator highlights all occurrences of the string in the document in yellow. The first hit is highlighted in green.
To close the search window, press ESC or the Cancel current search button. Any highlighted text will then return to normal.
As a quick way to highlight text found using Text Search, click the Highlight Search Results button in the search bar and select one of the predefined colors, or click Current Marker to use the currently set marker. All search results will be automatically highlighted using Marker annotations.
As a quick way to underline or strike out text found using Text Search, click the Underline Search Results or Strike Out Search Results button in the search bar and select one of the predefined colors, or click Current Pen to use the currently set pen. All search results will be automatically underlined or stroke out using Pen annotations.
