A la this Stack Overflow question, "click to copy" for arbitrary spans of text would be handy. i.e. when authoring/editing a page, I'd like to be able to select a span of text and then maybe click something in the editing toolbar or use a keyboard combo to make that span "click to copy-able." Then when the page is being viewed, there'd be a small icon to the right of that text that could be clicked to copy it. There'd probably also need to be some visual indicator that makes it clear what is going to be copied on click. This would be similar to the click-to-copy functionality of code snippets, but would be inline instead of requiring a full-on code block (and the text wouldn't necessary be code itself).
