How can list local file using lftp

Question

I'am on Ubuntu 19.10 and using lftp 4.8.4

from lftp help, I see, I can use bash command using '!'

I like to list my local file: not remote!
ls list remote file
!ls, !dir, !dir list remote file too lls unknown command

lpwd give me current local path but I like to list local file too!
Have I to open a new terminal to list local file?

Can you help?
best regards,
Leonardo

P.S. On man page I read:

  !ls
  To do a directory listing of the local host.

but not work!
