In Teams, now we can quickly search for any word within a Single Channel or in a chat. For searching there are two options available:
a)Using Shortcut Key
Go to the chat or channel, press Ctrl+F (or Cmd+F for Mac), then type what you want to search for. You’ll get results from just that channel or chat.
b)Using Search Bar:
In Search Bar Type \Find enter then type channel name and username enter and then type word you want to search. You’ll get results from just that channel or chat.
