I've had success getting basic paging by piping content to more, for example:
ls -l | more Or, if you want color output for use cases like syntax highlighting, you can use
ls -l --color=always | more This results in output that I can easily page through one screen at a time. I haven't tried @uther's modification to ~/.screenrc but that does seem preferable as a lasting solution when a mouse is available.
To try this out, you can go to this BusyBox emulator and then...
cd ~/bin ls -l --color=always | more Use the spacebar to page through the results of the ls -l command or use the enter key to move through results line by line.
