My ideal behavior would be that the itemize environment continues as if the branch inset is not even there. Similar with an enumerate (this would be helpful with exam documents). e.g., suppose I have: 1. an item 2. zanother item 3. another one. If I select all of the second item (i.e., put cursor just to the left of z and go to the end of "m"), and insert a branch, if that branch is turned on I want it to be the same as above; and if the branch is turned off I want it to be: 1. an item 2. another one. From what I understand, part of the hard part is not starting a *new* enumerate environment after the branch inset. Scott
