Multiple Highlight
extension adds a button to your browser toolbar area to bring real-time multiple word-searching to your browser. The default word separator is space but you can use ';' and ',' as the word separator if space is used frequently in your queries and is not meant to split words. This extension searches the currently active document and highlights the matching terms in different colors. You can press the Enter key to search the next occurrence or press the Shift + Enter combination to search for the previous occurrence. You can even define a keyboard shortcut to open the popup window with keywords. By pressing the ESC key once, the search query is erased and the second press on an empty search box closes the popup window and brings the focus back to the page.
