Without login via SSH to remote host,
we can securely copy or transfer using scp command.

Consider this case:
After we login with SSH to remote host, what utility can we
use to securely copy from remote host to my laptop
(while still inside SSH)?

Addendum:
I am going to try scp while in SSH mode....
Answer:
Nope. it does not work because while already in remote host I cannot access my laptop. The laptop is not accessible from WWW since it has a local private IP.

For all practical purposes, scp is ssh for files.

I know of no way to copy a file over ssh when you are logged into another computer via ssh. That's why scp exists.

You can't go backwards to the client machine unless it also has an SSH server running and is accessible. Better to open another terminal window in your GUI and do "sftp" or "scp" there, leaving the original remote session open.

If your client only has a single console and no options for any more, then you could suspend "ssh"
with ~^Z and with "ssh" in the background, run "scp" However, most GNU/Linux systems have multiple consoles you can get to with ctrl-alt-f1, ctrl-alt-f2, and so one up to f6. Or you can run "tmux" in your console.

But, again, if you have a graphical session running just open another terminal window.
