Hi Michael,
The Extend-skip-done works, though the trim-mutual-skip-done is not really complete?

That one skips the initial "select which type of trim" and goes straight to mutual, though stops there waiting for a done, as if you want to select pieces to "keep or remove", which I guess is a shortened version of the trim command, useful.

But shouldn't it just do the mutual trim and end? Maybe I misread the original post. Keeping the 2 added commands congruent though, it should just end I think.....
