I suggest a two-step solution:
map <Esc>x <M-x> " IMPORTANT: do not use :noremap here
map <M-x> whatever
This way, for all the mappings thus defined, Esc and Meta will be
interpreted the same way. You may also want to set timeouts as follows:
'timeout' (boolean) on
'timeoutlen' (milliseconds) slower than your slowest typing speed for the
{lhs} of a single mapping
'ttimeoutlen' (milliseconds) faster than your fastest typing speed but
slower than the interval between successive bytes sent by the system for a
single keypress.
Best regards,
Tony.
