I am just starting with PyCharm. I wanted to use more_itertools, which is not installed. The video here says I can click on the name and press alt-enter and get a menu that has an install and import option. If I select and press alt-enter, the menu I get just has the options 'Rename reference', 'Ignore unresolved reference', 'Adjust code style settings'. How do I get 'Install and import'?
