If the Add Branchpopup menu item is used, the new branch is placed below the others.6.5.6.2. Drawing BranchesTo create a branch in parallel with existing data on a branch, move the caret to one endof the data on the existing branch and get the branch popup menu. Choose the DrawBranch popup menu item. Move the mouse to the other end of the data on the samebranch and left click there. A branch is created between the two points. Branchescannot be drawn between two different branches, only between two points on the samebranch.6.5.6.3.
