As you may recall, I'm a big fan of keyboard shortcuts, and generally prefer those over using a mouse.
Still, there are keyboard shortcuts that are not comfortable, especially those that require the control/alt key in combination with a F key. For instance, Alt+F4. The reason for this is that one must lift at least of on his hands from the keyboard in order to use this combo.
Luckily, someone at Redmond thinks like me, and in Windows 7 (didn't test on other versions of Windows) one can use Ctrl+W to close the current explorer (the file management tool) window. Just like in your favorite browser and preferred IDE.
Too bad that in order to edit the current location, one still needs to use Ctrl+F4. I'd expect Ctrl+L to work. Anybody from MS reading this?
