Hi,

For xterm*,  you might be able to try these instead of a mapping that 
starts with <Esc>, since that can sometimes lead to messing with timeouts 
and/or having a delay when pressing <Esc> to leave insert mode etc.

  exec "set <xHome>=\e[1;*H"
  exec "set <xEnd>=\e[1;*F"
  exec "set <xUp>=\e[1;*A"
  exec "set <xDown>=\e[1;*B"
  exec "set <xRight>=\e[1;*C"
  exec "set <xLeft>=\e[1;*D"

thx,
-m
