The default of screen means all text currently on the screen. all means all the screen+scrollback and selection means the currently selected text. first_cmd_output_on_screen means the output of the first command that was run in the window on screen. last_cmd_output means the output of the last command that was run in the window. last_visited_cmd_output means the first command output below the last scrolled position via scroll_to_prompt. last_non_empty_output is the output from the last command run in the window that had some non empty output. The last four require shell_integration to be enabled. Choices: screen, all, first_cmd_output_on_screen, last_cmd_output, last_non_empty_output, last_visited_cmd_output, selection
