I just discovered tag templates in Arbortext and strongly encourage any Arbortext user to start using them!
Where to find: Tools > Tag Templates
Use to create and insert frequently used sets of tags and content. So far I have created tables where I only need to add cell information.
Glad you like the feature! I've always encouraged its use, I think it can save a lot of time (especially with tables!).
For anyone interested, I created a quick video tutorial on this a while ago, available from PTC University's Learning Exchange (it's free to watch).
