[LAU] all-track splice and move in Ardour

This is probably something that should be on the Ardour list, but I'm not subscribed there, and I seldom enough have questions about Ardour to subscribe... What's the most logical (and safest) way to take a section out of a whole timeline, across all tracks, and move it somewhere else? Probably describing this in computer terms would be too unwieldly for such a simple idea -- basically I want the equivalent of a tape splice. If it's necessary to individually move all the affected regions on all the affected tracks, I can, but I wondered if there's some simpler way. Also, I noticed some documentation saying the splice feature was unsafe. (I'm using Ardour 2.7.1.) I'm working on one of those songs where all the ideas came together, but in the wrong order. I've got a section about three-fourths of the way into it that really should have been the beginning... -- + Brent A.
