Normally, highlighting a module and pressing Ctrl + Q will work for modules / classes / objects / functions in standard libraries. You can also try calling "help" in the python console, especially if what you want to get is what you need to import first. For example, to get the "Workbook" documentation, you can type help (openpyxl.Workbook) to find out more, simply by pressing Ctrl + Q, answer "No Documentation Found".
