Opened Files Browser mode displays a convenient list of pointers to files that are frequently accessed. These files are not necessarily part of the project code, though they are kept with the project. For example, when you select Build|Make or Build|Rebuild, the files in the Project tree are compiled, not the files in the Opened Files Browser.
When you click a keyword in the Content pane, right-click, and select Browse Symbol At Cursor, the source file for that keyword is added to the Opened Files list, and the Opened Files pane is automatically selected.
Click the left-arrow icon above the Opened Files list to return to the previous group of working set files.
