Instructions on Typing in PDF Forms
If the PDF form you're accessing allows for input of data, tab from field to field and type to fill in the blanks. The mouse or Enter key will check and uncheck a box. Acrobat Reader will not save data that's been input into fields. Print the completed form before closing the file. Some portions of a form cannot be completed electronically; you may still need to circle a choice. Remember to sign the form.
NOTE: Access to PDF files requires the Adobe Reader. Most computers have the Reader pre-installed. If yours does not, you can download a free copy from the Adobe Web site. Be sure to check the Adobe System Requirements page to determine which version of the Reader is best for your system.
