My company is in the process of changing its name. It has decided that it should always be written in lowercase - so let's call it matteo, not Matteo.

Using autocorrect, I have solved how to autocorrect if the word is accidentally typed capitalised in the middle of a sentence.

Using custom dictionary I think I have solved how to prevent the word being capitalised at the start of a sentence. But this only seems to work if I use single space after a full-stop (period); with a double space, it auto-corrects to upper case).

And nothing seems to prevent capitalisation on a new line/paragraph.

Any advice gratefully received.
