ALT+S requires TWO confirmations. Can this be switched off?

[Morphoice]

Ahoi,

I'm pretty sure you all know hitting ALT+S requires two confirmations, which conditioned me to hit Enter twice in pretty much every other software I ever use, when I save something. This is causing real problems and damage....

Is there a way to turn this off and have ALT+S work like in any other program?

cheers!
