When I pres ctrl+shift+F to search across all the files in the current scope, I get a new window listing all the files that contain that search term.
How can I quickly open all of these files?
Hold down the F4 key from the Search Results screen, and it will "Navigate to next match" - which causes it to open each file listed in the results.
Just a small note, if you are getting 10+ matches per file this method starts to fail because it gets slow.
