Use shortcuts for Gmail System Labels to perform power searches quickly and with minimum typing.
Given Google’s heritage in search and overall mission (“to organize the world’s information and make it universally accessible and useful”) it’s no surprise that Gmail comes with some very powerful search features.
We’ve posted a previous tip on searching within Gmail - Gmail advanced search tips and we’re following up with some more options for power searching with Gmail System Labels.
These search methods effectively use shortcuts for system label names
They require the syntax: l:^ (that’s a lower-case letter L; a Colon; a Caret or Hat symbol)
In the example in the image we show l:^t which is a search for starred messages.
Of course you can combine these search strings with other search criteria too.
