I use Emacs now but I used Textpad (https://www.textpad.com/home) for a long time. It's a very light editor with syntax highlighting and large file handling.

Textpad is good for large files but that is the only thing I use it for (F5 to search - are you kidding me). Also, I don't think it is free.
