Productivity thought: I was just writing an email, and I wasn’t sure about the spelling of a word. It was all over in a few milliseconds, but what I found my fingers doing was to start typing the first few letters of the word and then I pressed CTRL+Space. If you use an IDE which has “code completion”, you’ll will know where I’m going here… I was expecting a list of matching words to appear, from which I could pick the one I intended to use. Of course, it didn’t. I think it’d be a good feature to have, and would really mean that I never have to learn how to spell.
