Support search with terminal UI

[gxxcastillo]

I really like the new terminal ui but unfortunately, I have been unable to do a text search for content that is not currently rendered to the window.

Unfortunately, this means I can not use it since anytime there's a target failure, I can't not search in the terminal to find the cause, instead I have to manually hit the up arrow which is tedious if there are hundreds or even thousands of lines of output

While it is possible to copy the output of a task to clipboard (simply type c on selected, non-interactive task) and then paste it an editor with a great search capability, it'd be lovely to have that functionality integrated into the TUI imho.
