How do you expand and collapse workflows?

My workbook is getting hard to add workflows because of its size. I need to collapse the workflows. The Help file says there is a button on the tool bar to expand and collapse the workflows. I can't find it in Toad 5.3 or 5.6

Just did a quick check on my 5.6 layout, and yeah, you're right, there's no said button, even though it's mentioned in the Help File. Quest Dev take note.

In the meantime, you can right-click on any of your workflows to see the collapse/expand icon, per below...
