Several CAT tools have this very useful feature: with one keystroke or button I can copy ONLY the tags in the source column to the target column. This allows me to then translate my content around the tags.
Presently, with QuickTag Insert, I can only do one tag at a time, making it pretty useless to me (or at least, I don't use it) since it's faster to copy/paste. The problem with that workaround is that then I spend scads of time deleting the source text.
