Inserting an Event Tree Branch
You can insert any number of branches (event sequences) in the event tree. Branch insertion behavior is specified by properties selected under Event Tree in the System file properties. For more information, see Event Tree System File Properties.
In the event tree, you can insert a branch for any column but the last column by doing one of the following:
Right-click the column and select Insert Branch.
Click the column and then select Insert > Branch. The new branch is inserted. Additionally, subsequent branches are inserted to each of the following columns until the end of the event tree is reached.
You can specify branch properties immediately after the insertion of a single branch or after the insertion of all branches.
