If an answer is accepted it often should also be up-voted because it is helpful. However, you might forget to up-vote it even though you are reminded to (also if you have less then 15 reputation you cannot up-vote). To correct such mistakes, it might be useful to have an effective way to find answers that you have accepted but not up-voted. As far as I know, there is no way to track which posts you have voted on and, thus, there is no way to find accepted answers that you have not up-voted (I take this to be to enforce anonymity of voting). So I wonder if there still is a way to find answers I have accepted but not up-voted?
A similar mistake to forget up-voting accepted answers is to forget accepting up-voted answers. There is an effective way to spot this mistake. Questions for which you have accepted an answer are easily distinguished from questions for which you have not an accepted an answer by them differing in color in the question list. You can also easily find them among the search hits for "user:me hasaccepted:0". The same does not go for answers that I have accepted but not up-voted because typically most of your questions have accepted answers so you would have to go through them one by one anyway.
