Very nice !!!

That specific capability is something that I've personally never run into.

When working on a program, which is my main usage of editors, I'm very careful
of what I'm doing.  Mass substitutions can drive a stake through your heart
if not very specific about what's happening.  Thus, I'm not a user of some advanced,
and even normal, capabilities.
