If you use Gmail for business correspondence or even if you have a lively inbox, you have probably run into the situation where you a certain email thread that just goes on and on, and you’ve lost interest. However, you might want to find the information contained in that thread later.

As I discovered recently (literally in the last 5 minutes, by @abacab on Twitter), Gmail has thought of you. It has the ability to mute a conversation, which means you won’t see any further postings. The conversation will continue, but you will be blissfully unaware until you do a search or un-mute the thread.

The hotkey to mute is M when you have the conversation selected.

You can find more about the mute feature in Gmail’s Help Center.
