The tone I currently have set for SMS alerts (incoming texts) lasts for several seconds, to increase the chance of me hearing it when I'm in a noisy environment, in a different room to the handset, etc.

Sometimes, however, I would like to be able to manually silence the alert rather than letting it playing all the way through, e.g. when the 'phone is close by, I'm in a quiet public area, etc.

On previous Nokia smartphones I've owned, I could do this simply by pressing a button, sliding the unlock switch, tapping the screen, etc. This meant that I could quickly silence an alert without even taking the 'phone out of my pocket.

On my N900, however, the only way I've found to silence an SMS alert is to open the incoming text message, which can take several seconds to do when the handset is locked and in my pocket (and means making even more noise by taking the 'phone out).

Flipping the handset over doesn't appear to silence SMS alerts, as it does for incoming calls or alarms.

Does anyone know if there is an existing way to quickly silence SMS alerts on the N900, or if it would be possible to create a D-Bus script to do this that triggers on pressing the power button or sliding the unlock switch (I would try creating this myself, but don't know what I would have to do to stop a currently-playing alert)?
