I find it extremely hard to spot my own little typos in papers—especially math typos. Though minor, I think these type of typos can be dangerous since they can confuse reviewers, and sometimes leave them stuck at a point and/or lose confidence in the paper. This is particularly the case for conference papers where reviewers usually have little time. As a reviewer myself, I find that if a paper has many such typos, I automatically tend to categorize it in the somewhat lower quality range.

I know that one way to find little mistakes is to give the paper to a peer who can have a fresh and unbiased look at it. However, this is not always possible, especially near deadlines, where everyone tends to be short on time. So how does one effectively proofread (for math-related typos) his/her own work without relying on others? Any research done on this topic?
