On Linux, I'm used to using ^\ for find and replace.
On macOS, I'm getting this message: [ Xterm mouse tracking on! ]
If I press it again, it says [ Xterm mouse tracking off! ]
Rather than toggle Xterm mouse tracking, I would like to find and replace text.
Solution:
brew install nano
brew link nano
Launch a new terminal window, nano will now allow find and replace using the method you are used to using.
