I must have inadvertently pressed some keys whilst entering data in Word and
my document is now locked. How do I unlock the document and what keys must I
have pressed originally to lock it.

Thanks in advance of a reply

If this only happens in one particular document, try opening that
document and clicking on Tools | Unprotect Document.

If all new and existing documents are locked for editing, then
it's probably because you have not activated your Word/Office
software, or because you have an expired trial version of Office
2003. What happens if you start Word and click on Help |
Activate Product? If you are already activated, a dialog box
saying so will appear. If you are not activated, the Activation
Wizard will start. If you have an expired trial version, a
dialog box will prompt you to enter a valid product key or
purchase a key online.
