Plenty of times I've come back to my computer, typed my OS password expecting that it was locked, waited for my display's turn-on lag, and found that it wasn't locked (grace period). I type the password blind, but reserve the enter until I have visual feedback.
At least typical IRC clients don't transmit until hitting enter. Browser omnibars and Javascript can send away every keystroke as it happens. Now I want to search all my Google Docs for my passwords -- let alone other stupidity I don't care to share.
A long time ago in a lecture hall far far away a head of school was giving us a pre-exam talk of some kind. It was too all health science students. As he talked he logged into the system. With the projector showing what he was doing he missed the tab key and typed his username and password into the username field. I had a look round the room and no one else seemed to have noticed. On his desktop sat a folder titled "Exam papers" or something similar.
