The Gmail features armory would soon have a new addition - a Gmail Labs feature termed "Undo Send." The feature allows users to abort a typical "Oh, No!" email if they are quick enough to react 'within five seconds' - extendable up to ten - as the feature withholds the sending of all outgoing messages for that brief period.

The enhanced "Undo Send" Gmail feature - which will roll out soon - can be enabled by going to the Labs settings and turning it on.

Gmail already boasts of some other user-protection features, like Gmail's capability to determine whether attachments are included after the word "attached" is used in the body of an e-mail; as well as a Google Apps feature - in the corporate version of Gmail - which puts orange borders around 'outsiders' names for alerting users while sending confidential company information.

However, the new "Undo Send" feature is a cut above the others. It gives the users a second chance to retrieve a regrettable press of the "send" key, provided, of course, that they can act fast enough!

According to Google product manager Keith Coleman, the internal testing of the feature indicated that a five-second hold was sufficient for recalling an errant message, without bringing about an unnecessary delay in the conversation. Coleman said: "Adding a delay could be potentially frustrating!"
