Expression search in all opened files (tabs)

Very often I want to find a special expression not only in the activated file (active tab) but e.g. in all opened files.

Otherwise I have to search in the first tab, then switch to the second tab and push F3 and so on. If you have opened a lot of files this wastes some time, doesn't it!?

Menu -> Search -> Search/Replace in Files...
Then set the "Search Scope"
