People often ask why I contribute to open source projects or otherwise work on building automated tooling. They see me spending hours to automate a task or fix a bug that take seconds to do or avoid manually, in a way that the original XKCD comic says won't pay off. The disconnect seems to be that the comic and those people only consider time it saves me, not time it saves the tens to thousands to millions of other people who will use the script or patch or whatever when I publish it. So, here's a version of xkcd.com/1205 updated for making decisions that benefit a thousand people instead of just one.
Copy, cut, paste, undo. Use those keyboard shortcuts and if you work with documents for a notable part of the day you will save a half day a year or so.
I know some people who still do that with the right click menu. Then again, they don’t really copy-paste stuff very often. Maybe only once a week or so.
