Seeking an Unusual Tool

Sort of a glorified keyboard macro that lets you start a sequence that includes Ctrl-F (to do a find in a web page) but also able to search for a displayed button (like "PDF" or "Next>") and click that button.  There a number of keystrokes and clicks required to go from one PDF page, back a level, then hit Next> to go the next matching page then click PDF then Ctrl-F to find the word "murders".  If you know of a handy macro tool like that, could you inform me?
