Start by typing the beginning of a function name and hit Ctrl + n to bring up the autocomplete list. You can navigate the list using Ctrl + n and Ctrl + p. For example, open welcome.py, enter insert mode, and start typing the first two letters of a function name: pr (prepare_ingredient). Press Ctrl + n. This will bring up a list of available options:
