I submitted a transaction via Mist with the fee slider at the leftmost position. Nothing happened for a day now, so I suspect that the displayed gas price has been to small, although Mist told me that the transaction is likely to be executed in a few minutes.
I searched the internet on how to cancel a transaction and found that in principle there is no way.
However, the transaction does not even show up on etherscan yet, so I suspect that it might not even have been published(?). If it is so, is there a way to stop Mist from doing so?
I also found that you can send another transaction with a higher gas price but the same nonce such that only the latter transaction is executed. I could send a zero-valued transaction to myself with the same nonce. Is there a possibility in Mist to find out the Nonce of the displayed transaction and to send another transaction with the same nonce?
Edit: The linked "possible duplicate" does not explain how to get the nonce from a transaction in Mist and submit a new transaction with the same nonce.
