Nudge and Buzz
After really really long time, today I sneaked into Windows Live Messenger and Yahoo Messenger. There has been a lot of things that have changed in both over the course of time When I mean a lot of things, I really did mean a hill and valley difference. When I was casually playing around these instant messengers, I found a real good feature called 'Nudge' in Windows Live Messenger which corresponds to 'Buzz' (CTRL+G) in Yahoo Messenger.
Basically it jolts or shakes the instant messenger window and plays a buzz sound on the speaker to attract the user's attention. Good that Windows Live Messenger has brought the Nudge feature based on the classic buzz feature of Yahoo Messenger. Similarly, now Yahoo Messenger seems to be a comprehensive Instant Messaging platform in that you can use it to chat with Windows Live Messenger buddies also.
