Many writers use index cards, or 3 by 5 cards, as an organizing tool before writing their scripts. Using a separate card for each scene, they jot down what happens in the scene, where it takes place, etc.
Numbering each card shows the flow of the story from scene to scene. Adding a scene is as easy as inserting a new card between two others. Moving scenes is equally simple, though having to renumber the scenes each time is a chore.
When satisfied with the outline created with the index cards, the writer can expand on that information to write the individual scenes that form the story.
Now Screenwriter brings you an easier way to work with index cards—on your computer screen with Electronic Index Cards.
The information you write on each card transfers directly to a scene in your document. The top line on the card becomes a Scene Heading, and the description becomes Action. Moving an index card is performed using the familiar Drag and Drop method—and Screenwriter automatically moves the scenes in your script and renumbers them for you!
When you're satisfied with your index card outline, switch from Index Card View to normal Document view. All the work you did on the index cards is there—an outline ready for you to expand into a script.
