    window.bind('<Control-d>', find2)
    window.mainloop()
    
if __name__ == "__main__":
    main()

Sample file:

<html>
<head>
<title>Just a test</title>
</head>
<body>
<p>cat</p>
<p>black</p>
</body>
</html>

The first find operation (Ctrl+F) matches 0 hits and the second (Ctrl+D) matches 2 hits.

Great point. I changed the search flags to re.MULTILINE. Let me know if it works!

It now works. Thanks!
