I am reading Emacs Lisp Reference and can not understand the following
paragraph:
For historical reasons, Emacs treats the <DEL> character as the
control equivalent of `?':
?\^? => 127 ?\C-? => 127
As a result, it is currently not possible to represent the character
`Control-?', which is a meaningful input character under X, using
`\C-'. It is not easy to change this, as various Lisp files refer to
<DEL> in this way.
What I understand is :
?\^? = <DEL>
now we can not represent `Control-?' with `?\ " syntax.
Is it right?
What does "which is a meaningful input character under X, using
`\C-'. " mean ?
Thanks
