There are lots of symbols (alpha, beta, gamma, degree …) which don’t have buttons on your keyboard but you can still use them in documents or anywhere you want.
Different OS have different built-in tools for adding such symbols. In Windows and Linux there is tool for adding symbols, named as Character Map. Tool with similar functionality in Mac OS is named as Special Character Viewer. Here is how to access them in different Operating systems.
