Alphabetically sorting a bunch of text is something I need to do fairly regularly. Thankfully Emacs has a built-in function to help with that: `sort-lines`. It looks like this: Calling `M-x sort-lines` will sort all lines in the current region. Lines are sorted numerically, then alphabetically, and capital letters are sorted before lower-case ones (e.g. `A` will come before `a`). Emacs will only sort text in the highlighted region, so it's important to mark everything that needs sorting. Otherwise it can end up like this: `sort-lines` is one of those handy little functions that I never knew I wanted, until I was sat with a pile of unsorted text and wondering "I wonder if Emacs can help".
