using TAB, ENTER or RETURN to advance fields by force

[Admin]

Hello again. 

I want the user to go to the next field (by force)
by pressing either the TAB key, the ENTER key or the RETURN key. 

How
do I do this in code? 

I know you can write the following: 

on
enterkey 

 --go to field "MiddleName" 

end enterkey 

same with
tabkey. However, it does not work. 

I appreciate your help everyone.
