How can I highlight all signals of a signal class (net class)?
Using key [f] which stands for "find and select", you can highlight all signal segments or track segments of acertain signal class. See also the identical menu item in the "Edit" menu.

At the top right of the sidebar you can also search for the name of the signal classes in the search
line. Click on the binoculars. Also the selection assistant in menu "Edit" offers "signal class" as search criterion, see the Property column.
