[TxMt] "All" Command

Some of you may remember back in the mainframe days XEdit. One cool feature of XEdit was you could type all <pattern> and only those lines matching the pattern would be displayed. You could edit within this view.

It seems like something similar could be done in TextMate by using folds. I've tried to do it with a macro using find and bookmarks, but I don' seem to have enough control to select text between matches so I can send the Fold Selection.

I'm aware of Text->Filtering->Copy Matching Lines, but this creates a new window and any edits in that window aren't felt back in the original.

Anybody have an idea on how to do something like this?
