Add the ability to markup text (words, sentences) or images, so that when you single-click on it, it copies the text/image to the clipboard. Basically a hyperlink but instead of a web URL, it copies the text to the clipboard. Ideally done with a markup symbol so it can be automatically generated, e.g. !!!Click Text To Copy To Clipboard!!!

An example would be with a serial number, or model number, the ability to just one-click-copy, instead of click-drag-highlight + Ctrl+C would simplify the process.
