Nice way to hint that you are definitely being sarcastic, because cmd+something+3 surely and clearly is no way intuitive, contrary to the use of dedicated Print Screen key on Windows.
Just to point for the unfamiliar, the "hotkey" defaults for screen shotting are user configurable on macOS, in System Preferences/Keyboard/Shortcuts. In fact, shortcuts can be changed not only for all actions, but also menu items in any/all programs can be remapped to desired key combos, or indeed added for menu items with default hotkeys. This is actually staggeringly powerful, and frequently overlooked.
