Script Devleopment

Hi guys,
I am working on Testing Automation on Oracle Saas platform.
So I am developing my script over R12 environment and then testing it over R13 upgraded version, I have checked the selectors and aname for most of the time script is fail at some point even the selectors are dynamic.
Can we use ‘HotKeys’ for inserting values into the pop-up will that make the scripts more dynamic.
