Use less,

    emerge --ask --update --deep --newuse @world | less

Or screen,

    screen emerge --ask --update --deep --newuse @world
    # then Ctrl+A Esc to go into copy mode which can be navigated with up and 
down arrow keys

Or output to file,

    emerge --update --deep --newuse @world > emerge.log

    # then you can open it in a text editor and search around.
    # I took out the `--ask` so that it wouldn't prompt before starting
