The secret to the simplicity of pressing Tab and Enter to go from element to element in Screenwriter is its intelligent feature, QuickType.
Based on which Element the cursor is in, QuickType makes an informed guess as to what you'd like to do next. It places you in the logical next Element, and pops up a menu of possible choices.
For example, if the cursor is in a blank Character Name element and you press ENTER, a list of Character Names in your document pops up for your selection.
