Invert a selected region with the middle mouse button or spacebar. Undo the last edit with the 'q' key. Exit edit mode with the 'e' key. Use the GUI to see a list of completed edits.

The text lists each map fragment in the selection with the contig name and a **local** span in megabases along that fragment (not a single genome-wide coordinate). If nothing is actively selected, the current edit cursor range is used.
