Nothing drives me crazy like working on a file that another designer created that doesn’t know about InDesign’s Span or Split Columns feature. There’s just no need to create a separate Text Box just to have the headline go across the top of two columns of text. It’s a pain in the behind. Span Columns to the rescue!
Following close behind is when a designer wants to have two, three or more columns of bullet points in the middle of their text flow and doesn’t realize that you don’t have to create a separate multi-column text box in the middle of the text flow and then use multiple carriage returns to leave space for it. Edit the text above that separate text box and you have to move the text box with the bullets every time. Such a pain. Simply use the Split Column feature.
If you don’t know how to use them, Erica Gamet has a great how-to article at CreativePro on how to use Span and Split Columns feature.
