NeoCal for Palm OS User Guide
An alternative method for entering the registration information is available by copying all of the registration information from the registration email to the clipboard of the handheld device and then switching to the NeoCal application where the Registration dialog will be automatically opened with the registration information already entered for you.
For example, you might use the Palm Desktop (or Outlook) software to create a memo (or note) containing the registration information by copying and pasting it from the registration email. After syncing, open this new memo on the handheld and copy the registration information to the clipboard. When you switch to the NeoCal application, the Registration dialog will be displayed with the information entered into the appropriate fields.
