You may see people using this all over the place and wondered how they were doing it. It is probably not something Mm wants people doing, but here is how to get coloured bold text inside your game names and text gadgets.
If you use <term> in your text gadget or in a level title it will turn your cursor yellow and you can type bold yellow text
If you use <clue> you get bold Purple text.
To end the colour use </term> or </clue>.
This is not really intended as a feature and people are discovering other words that create different colours (I have heard that orange is available but they declined to share the word).
