I would say magit as an example. Single key presses for most actions. I often have that situation, when I share my screen and perform some commits and then people ask me whether I already commited X. I then think something like: "Uh, but I just did that, in front of your eyes." but then I remember the other workflow involving the normal command line or some clicky-gui kind of tool, that is just slower and is what others are used to.

Then maybe keyboard macros. Define anything you can input in a "tiling" way on your keyboard as a macro to let the editor perform it repeatedly. Approximate quote from coworker: "Sometimes you do things inconveniently, but what you do in Emacs was highly efficient."

Then running vterm inside emacs and searching and copying from the vterm buffers to use text elsewhere.

Of course org-mode as an extremely neat way of managing information and to do. I use it every day, a lot. I use it for notes, for to-do, for time tracking, for literate programming, for devops, for creative writing, and probably more.

Then the pain I get, when I see people closing their vscode, just to reopen it in another directory ...

Then the pain I see others have, when juggling a high number of editor tabs in intellij or vscode, instead of buffers that exist and can be switched to using keyboard shortcuts. I lost faith in tabs for code editors.
