Does anyone know if there is a keyboard shortcut to open the kmail window?
When I close/hide kmail (alt+F4 or Win+M on my current setup), it goes nicely to the system tray.
But when I want to look at my emails, I have to go and fetch the mouse to click on the tray icon to restore kmail (this is slightly annoying since both kmail is full of nice keyboard shortcuts and I don't need the mouse to reply to emails). Is there a key binding to do just that?

Many thanks

PS: I have KDE 3.5.9 and kmail 1.9.9
