I'm trying to find shortcuts to type some special symbols which seem to be used very often in my reading materials. So far I have figured out some like おんぷ for ♪, から for ～, ほし for ☆... but there are still several ones I couldn't find, especially ―, which is the most common of all. Is there any site that lists input commands for such symbols? I find it's really annoying to input them by mouse.
