I've told the story before about my 1st boss losing all his edits on an important document. As a speed typer there were a few expletives muttered and he started to redo his efforts. 17:29 and the same thing happened again.
I was staying in the office late because I was meeting friends in town so was witness to this happening a 3rd & 4th time. Before the 5th time he asked me to watch him to see if he was doing anything obviously wrong.
As he started to type "Functionality" it all became clear. Instead of hitting SHIFT F he was hitting CTRL F.
File Unload. "Do you want to save changes" No. There's an irony in having no fun with functionality
