[Feature]: Search in terminal contents (program output)

[groszdaniel]

Feature description

I suggest adding a feature to search in the output of programs (really just the contents of the terminal).

One can always pipe to grep or less, but in some cases (such as if you've already executed the program, or it's a program continuously running in the foreground, or you're unsure if it prints the relevant output to stdout or stderr) it's more convenient if the terminal program also provides a search feature.

Additional information

Several terminal programs, such as Konsole and GNOME Terminal* have it, attaching screenshot of Konsole as an example.

_{* Not the same as its GNOME HIG-compliant replacement GNOME Console, which doesn't have it.}

Legitimate request, can be looked into in future.
