I was just using gmail and came across a link about advanced search. I've never done more than just a quick search by typing in key words in gmail. So I gave it a shot.
I tried a few items such as label:trash and label:chats and it works great! I'll be utilizing this more now. I've posted this as a reference for myself and hopefully any of you who find this helpful.
What other functions of gmail do you think is useful?
