Text function to delete specific string of text?

[TsunamiZ]

Is there a text edit function to delete a specific string of text? I want to make a macro that deletes certain words to make it quicker and easier to rename some files, etc. Is this possible?

Replace "FromString" with "ToString" in %T1% found in Variable Modify String.

i tried messing around but can't get such a macro to work. can you be more specific? i want to create a macro to rename any file that has "word x" with "word y" [word y can also be just delete function].
