Keyboard Optical Illusion

[Asbo Zaprudder]

For those of us non-Windows users - what does Alt-F4 do?
...

Kills the window that currently has focus.

 

[Gepard]

Indeed. It's basically command + w for Windows.

 

[Nerys Ghemor]

Ctrl + W closes the window, too.

And I may have to try the compressed-air thing...don't own a dustbuster so that's probably cheaper.

I used CTRL + W to close tabs a lot in firefox.

ALT-TAB would be a harmless trick - "Hey, how did I end up here?"
