So we can replace and redevice the logic for he standard buttons on the detail pages such as delete,
I tried, but seems to me there is no go for the Save button. Am I right?
Seems that only applies to the standard buttons, which doesn't include "Save".  So what can I do if
I want some extra logic embeded in the "Save" action? Like when the "Save" button on salesforce is pressed, I also want the record to be created or updated on our company's side.

Thanks for your input.
