My "info" on emacs tells me after I do a M-x hexl-mode <enter> C-M-x should be the way to insert a character in hex. Does C-M-x mean Control m (or Control M) followed by an "x" ? Control-m or Control M gives me a Carriage Return, not a prefix to a further command. This is emacs from the cheapbytes four-disk set of debian; the emacs is version 19.34
Any suggestions will be appreciated. joeh
