The objects editor supports Favorite Searches which allows lists of objects to be quickly looked up.
Entering “fv:xyz” in the search bar loads xyz.txt from the game folder, and will match any of the lines in the file. Empty lines and lines starting with “//” (comments) are ignored. The .txt file extension was chosen because it is the notepad default.
For example this matches anything with “fire” in the name or Road Line Cap #1:
// Fire related props Fire // Specific road prop Cap #1 Road Line
Recursive usage of filters is supported, so multiple favorite searches can be nested, or other filter types e.g. “Tunnel mb:core” includes tunnels from the vanilla objects.
