In case you didn't take my advice, I want to share part of one of his tips that told me something I didn't know. For years I've had flyspell-mode enabled in all my text-derived buffers. It's nice to get immediate notice when you've misspelled something. What happens is that the incorrect word is underlined in red and I have to type 【Meta+$】 to see the list of suggestions.
A far easier method that Maughan wrote about is to simply type 【Ctrl+;】 to cycle through the suggestions. That works really well because most often it's a simple misspelling and the first suggestion is the one you want. It seems like a small thing but I've saved a lot of effort since I learned about it.
If you're interested in being on the list, see Maughan's comment on my original post. He says he'll probably move it to a blog but in the mean time he's kindly offered to add anyone interested to the list.
