Keyboard Shortcut - Screen Lock

Here’s an interesting take on the : Did you know? On Windows, the classic Win + L locks your screen instantly — but on Linux (depending on the desktop environment), it could be Ctrl + Alt + L , Super + L , or even Ctrl + Shift + L . On macOS, it’s Control + Command + Q (or Cmd + Ctrl + Q for some versions). Interesting twist: “The fastest way to protect your data is not a complex password — it’s a two-key reflex. Win + L turns your screen into a vault before your coffee hits the desk.” Fun fact: Some people remap their lock shortcut to something unusual like Ctrl + Scroll Lock just to confuse shoulder surfers. Others use AutoHotkey to make F13 (a key that doesn’t exist on most keyboards) lock the screen via script — forcing anyone trying to snoop to guess a key that’s physically missing. Challenge: Can you lock your screen without using the keyboard? (Try: Windows → Win + X → U → I — that’s two shortcuts away from the classic Win + L .)
