Why Microsoft chooses Alt+F4 to close a window

Summary

Windows users often question why Alt+F4 closes applications instead of the seemingly more intuitive Alt+Q. Raymond Chen, a long-time Microsoft developer, explained this decision stems from the need for universal accessibility across diverse languages and keyboard layouts. Relying on "Q" for "Quit" is not globally understood, nor is its key position consistent across different regional layouts like AZERTY. Therefore, Alt+F4 was selected because function keys are universally present and consistently located, providing a reliable, non-localized shortcut for all users regardless of their language or keyboard configuration.

For a long time, there is a doubt among lots of Windows users especially those English speaking users, that is why Microsoft chooses Alt+F4 to close a window instead of Alt+Q. Alt+Q is more comfortable to press for many keyboards, also Q represents Quit and it is easier for people to understand. Recently Microsoft answered this doubt.

Raymond Chen, longtime Microsoft developer and semi-official Windows historian, said the reason is that not everyone speaks English. It doesn't work that way in many other languages. You have to choose a common key sequence which people from different places can use, it doesn't need to be localized.

In addition, different keyboards have different layout because layouts can be customized. For example, if you are in France, the letter Q is not even at the upper left corner of the keyboard.  So if you choose Alt+Q as the hot key, you still need to find the letter Q. Hence Alt+F4 is a kind of safe combination because the Function key isn't going anywhere and it's rarely customized.  You can find it even if you are using different keyboards.
