The traditional find window has the advantage that it is a text window and one can easily copy (parts of) its contents. Find Reference doesn't have this property, I know that it lists the matches categorized by the file name and therefore it is a tree, but still I miss the feature. Or, at least a button to copy the whole content to the clipboard. I would like to further process the results with shell scripts.
I am using the 1619 build. The copy from either context menu or by pressing ctrl+c indeed works, but only copies the actual line, or, if a file name is selected, the matches of a file but still not all the results what I really need. I have matches in 25 files.
Would the IDE's find in files work better for you?
Alternatively some form of macro system might work well. You can press Delete to delete a file and all of its results from the Find References Results list, and then use CTRL-C to copy the next block. You just need a program to send keyboard events to the IDE.
I know its not an elegant solution, but with the right software it is easy to do.
