RE: Tips & Tricks, changing layers , fast end easy, keyboard shortcuts, scripts

RE: How and where to find DRC highlight information.

It would rather help to know which DRC tool you're using. Is it Dracula, Diva, Assura, PVS, Pegasus, Calibre, IC Validator, Hercules or something else? Knowing the version would help too. Andrew.
