Many a times you may close the yahoo messenger which minimizes it to the system tray or, the yahoo messenger window may lose focus while you have some other application over it or have minimized it to the taskbar. You may either have to double click on the messenger icon in the system tray or manually open it from the taskbar in such cases.

Yahoo Messenger 9 saves you the trouble of using your mouse to bring the window into focus, simply pressing the Windows + Y will bring the yahoo messenger window on top of other windows thus allowing you instantly send a message to your contacts without even touching your mouse.

Though its hardly been 12 hours since I began using this feature I am already addicted to it. To enable this feature go to Messenger -> Preferences or use the short cut key Ctrl + Shift + P when Yahoo Messenger is in focus.

Select the General option and check the box next to Press Windows + Y to open Yahoo Messenger & start a Conversation. Click on Ok and you will be able to use the hotkey now.
