Is there a quick way to 'Find and Replace' across a project

[Frank]

I don't think there's anything built in. Requested here also:

IDE Wish List Collation

Search (and replace) in all open files, with results shown in a panel. (I'm thinking of what notepad++ does. This was also requested on the help site. The lack of this feature is one of the main reasons I don't use RStudio for anything but R Markdown projects yet.)
