Fill a form

Leave that unticked and the form stays a form: whoever receives it can still edit the boxes. Tick it and the answers are drawn into the page and the boxes disappear — right for something you are about to send, wrong for a draft.

Values go into the real form fields, not typed on top, so the file opens correctly in Acrobat and prints correctly. A scanned form has no fields to fill — use theeditor to type on top of that instead.
