Ok so this is just a little feature on OSX operating systems (Apple) and its nifty. Just basically auto corrects common spelling mistakes. Anyway I couldn't find a video tutorial so i made one myself if anyone is interested see below.
Well I use it for things like youre to correct it to you're or if I just type ou instead of you. Or common names to capitalise. I'm sure there's someone who'll appreciate it lol.
AAhh yeah, them lazy people who can't be bothered to use shift. Does it put full stops on the end of a sentence? and question marks at the end of a question?
