To configure or use a mouse to copy and paste at a terminal on a FreeBSD system, you can use the tmux utility.
tmux is a terminal multiplexer that allows you to use a mouse to copy and paste at a terminal. It is not installed by default on a FreeBSD system, but it is available in the FreeBSD package repository.
To install tmux, you can use the pkg command. For example:
pkg install tmux
This will install the tmux utility on the system.
Once tmux is installed, you can start a tmux session by running the tmux command. For example:
tmux
This will start a tmux session in the current terminal.
To copy and paste using a mouse in a tmux session, you can use the following steps:
Press the Ctrl + b keys to enter tmux command mode.
Press the [ key to enter tmux copy mode.
Use the mouse to select the text you want to copy.
To copy the selected text, press the Ctrl + w keys.
To paste the copied text, press the Ctrl + y keys.
You can find more information about the tmux utility and its options in the tmux documentation or by running the tmux -h command.
Alternatively, you can use a terminal emulator that supports mouse integration, such as xterm, gnome-terminal, or konsole, to copy and paste using a mouse at a terminal.
You can find more information about terminal emulators and how to use them to copy and paste using a mouse in the documentation for the specific terminal emulator you are using, or by searching online.
