       _S_c_r_e_e_n  is  a  full-screen  window manager that multiplexes a physical
       terminal between several  processes  (typically  interactive  shells).
       Each  virtual  terminal provides the functions of a DEC VT100 terminal
       and, in addition, several control functions from the  ISO  6429  (ECMA
       48,  ANSI  X3.64)  and ISO 2022 standards (e.g. insert/delete line and
       support for multiple character sets).  There is a  scrollback  history
       buffer  for  each virtual terminal and a copy-and-paste mechanism that
       allows moving text regions between windows.
