** Documentation
Im interested in using [[https://devdocs.io/][devdocs]] instead, which is similar, but keeps it all /inside/ Emacs (and works on my Linux system). Two Emacs projects compete for this position. The Emacs [[https://github.com/astoff/devdocs.el][devdocs]] project is active, and seems to work well. Its advantage is a special mode for moving around the documentation.
Used to use the Dash project for searching documentation associated with a programming language, but that hardly worked on my Linux systems.

The [[https://github.com/blahgeek/emacs-devdocs-browser][devdocs-browser]] project acts similar, but with slightly different command names. Its advantage is that it allows for downloading docs and having it available offline, in fact, you cant search for a function, until you download its pack. This is slightly faster because of this.

The =devdocs-lookup= command attempts to guess which documentation it should display based on the mode, but if Im editing YAML files, I actually want to pull up the Ansible documentation, and probably the Jinja ones too.

** Code Folding
While Emacs has options for viewing and moving around code, sometimes, we could /collapse/ all functions, and then start to expand them one at a time. For this, we could enable the built-in [[https://www.emacswiki.org/emacs/HideShow][hide-show feature]]:
