When working on an Android project, you make lot of changes in lots of files. It will get increasingly difficult to recall where you made modifications as the number of changes increases.
To find the files you’ve recently visited, go to View -> Recent Locations (Ctrl+Shift+E) and you’ll get a list of the files you’ve recently visited.
To see only the files you’ve recently edited, press Ctrl+Shift+E again, and you’ll get a list of the files along with the preview of changes you made.
