No, but you could create a replacement macro and then assign that to a keycombo.

Start with this replacement, assuming your word is foo and you want to match its case, i.e., you don’t want to match FOO or Foo, only foo:

Find: (?-is)^.*?foo.*\R
Replace: make sure this box is empty
Options: Wrap around, Regular expression
Action: Replace all

This would match food and other parts of words containing foo as well, but if you don’t want that there are ways around it…
