Pre-defined semantic queries

When browsing a source file in the Web interface, clicking on different nodes (bold text) brings up a few buttons for pre-defined semantic queries for that node type in the top right corner of the screen.

After clicking one of those buttons, the query is executed and the first result (if there was any) is shown.

Results can be browsed with the appearing Prev and Next buttons. The total number of results as well as the currently shown result's number are displayed under those buttons.
