- the enter command in Finder is a UI convention. Some Linux DEs have a similar one in their file managers. - the OS uses Emacs key bindings throughout in standard input fields. Try it. - Search for “Magnet” or, if you’re a tiling person, “Amethyst” - Mice just work. You may get a dialog for weird HID devices, but I don’t get why you mention a tutorial - hot keys are configurable in every single application - check the system preferences. - brew is not the only option, you can also look into MacPorts (but I wouldn’t recommend it) - there is an “open” CLI command that you can use for to invoke non-CLI apps that do not register themselves in PATH. Use “man open”. Also, look into native CLI tools like sips, etc. There is a lot of CLI goodness in macOS that impatient people overlook.
