Hi,
Is there any way to execute a command automatically, after I had read an unread message?


Optional information:
I set my unused capslock led to blink, if I got a message in Kopete, via executing a command. But the LED doesn't stop to blink, if I had read the message, and I have to turn it off manually via executing a command.

Unfortunately it doesn't look like this is possible as such.
One thing you could do is configure KHotkeys so you just need to press a shortcut key to clear the status. Alternately, if you always reply, add the command to the "Outgoing message" notification.
