This PSD file will demo the Skip Tag. This will allow you to do as it says, skip either a layer or folder from processing in the output. Add dev notes, comments, etc.
Skip is not Remove
When you skip elements in your design, the element area is still calculated in your output. This makes Skip Tag great for margins and layouts, but may also lead to display errors when not correctly used. If you do not want the element’s size (area) measured in the output, then remove it!
Testing the PSD
Use Exports view to see the output of the document when using Skip Tag.
