Can you explain how to get into list mode? I have been clicking on each link of the taxiway to change the designation, its super slow that way.. Never had so many messed up taxiways like in MSFS.@SMWilliams. You can rename a full taxiway by going to list mode. Next, sort the list by taxiway name(A,B...). Then select the specific taxiway letter and edit. ADE also has a group select shortcut which you can use to select all the taxiway links in a taxiway.
There is also a utility for validating taxiway sign integrity but it has not be updated for MSFS:
Taxi Sign Validation Program 0.9c (beta)
Utility to provide an automated method of checking large projects for incorrectly labeled taxi signs. This should be considered a beta program as it has never been tested on any system other than the Authors. It makes no changes to your airport...www.fsdeveloper.com
