DESCRIPTION
     The xterm program is a terminal emulator for  the  X  Window
     System.  It provides DEC VT102 and Tektronix 4014 compatible
     terminals for programs that  can't  use  the  window  system
     directly.   If the underlying operating system supports ter-
     minal resizing capabilities (for example, the SIGWINCH  sig-
     nal  in  systems  derived  from  4.3bsd), xterm will use the
     facilities to notify programs running in the window whenever
     it is resized.

a vt102, you may recall, doesn't have modifiers...

xterm is (fortunately) smaller than Emacs, but it is documented.

if you read the manpage, you may notice this near the end:

start with man X11.
