Remove icon from notificacion area/system tray (caffeine)

[xingular]

Hello everyone,

new in LMDE here MATE desktop.

I have installed caffeine (adding karmic repository) and is working ok. But is an old version and it doesn't have the option to "remove the icon from tray/notificacion area".
How can I do this "manually"?

Or: How can I install a more new version?
Or2: Any oder idea to "lock" the screensaver when I'm watching some flash stuff in youtube, for example?

The reason is that I have a 15" screen: I need space!

Thank you so much.

You don't need Caffeine. Right-click on a panel -> Add to panel -> Inhibit Applet
And remove the Karmic repository ...

Thank you for the tip. Actually Karmic repository is removed
But I'm searching something more "automatic". The PC is not only used by me, but also by members of the family who they only know how to open the browser hehe.
Normally the "problem" is with flash videos like youtube.

It's only a click away. If you insist on Caffeine: It's now located at Launchpad. There a newer versions but they are for Ubuntu not Debian!
I'm not exactly sure what the culprit is. Either it's MATE not reporting correctly to DBus or a problem with gnome-power-manager.
It's not solved in mate-desktop.org versions. I hope it will be.
