When editing my pages, I'd like to be able to replace multiple lines of text in multiple files. Normally I use ConTEXT to edit my pages. In ConTEXT I can open multiple files and find/replace a single line of text in all files.

I tried HTML-Kit, which would let me replace multiple lines of text, but only in one file.

So, is anyone aware of an editor that lets you replace multiple lines of text in all open files?
