12.27.6 Alternative
Symbol:
This command (category 'SFC') available in the SFC Editor transforms a parallel branch
to an alternative branch.
Notice that after a branch transformation you must check and adapt the chart
appropriately, that is you must arrange steps and transitions as required for the
respective type of branching.

12.27.7 Insert branch
Symbol:
This command (category 'SFC') is used in the SFC-Editor to insert a branch left to the
currently selected element(s).
See Insert branch right for further information. The difference is just that the branch is
inserted to the right of the currently selected step.
12.27.8 Insert branch right
Symbol:
This command (category 'SFC') is used in the SFC-Editor to insert a branch right to the
currently selected element(s). (To insert it each left to the currently selected step, use
command Insert branch.)
• If the uppermost element of the current selection is a transition or an alternative
branch, an alternative branch will be created.
• If the uppermost element of the current selection is a step, a macro, a jump or a
parallel branch, a parallel branch with label "Branch<x>" will be inserted. This is a
default label name where x is a running number. You can edit the label name. The
branch label might be used as a jump target.
• If currently a common element of an existing branch is selected (horizontal line),
the new branch will be added to the existing branches on the right most position. If
currently a complete arm of an existing branch is selected (horizontal line), the new
branch will be added directly right to that one.
Note: Notice that branches can be transformed by commands 'Alternative' and
'Parallel'.
Examples:
Parallel branch:
In the following picture see a new parallel branch, created by command 'Insert branch
right' when step11 was selected. Automatically a step ("Step2" in the example) gets
inserted.
