Stop Transaction on SAP Portal

When I access a Transactional iView from Portal, it does not show the icon on the top left most corner like in ECC, which will display the below Menu ,when expanded.

Stop Transaction

This icon and menu comes up (as stated above) when the transaction is accessed from backend (SAP). Can I get this same functionality on the Portal or how can I accomplish Stop Transaction at least. On the portal when you execute a transaction you loose the cursor and can't enter a transaction to kill the session. In SAP you have HOT KEYS is there on for that menu?
