M-x hexl-find-file
for first time users, type `C-h m' to see the useful key bindings
after you are in hexl-mode.

发帖数: 2074 | 8 in PC, i found it is Esc.
now i can see a file in hex mode, but when i try to insert a hex byte,
for example, i typed in C-M-x, then type a number 41, to wish it can
be inserted into the file, but it always says:
Point is not on a character in the file
what's wrong with my operation?

Meta key, like Ctrl key.
It was a legacy key on mainframes used in MIT during 1970s.
Now on PCs, it is normally mapped to Alt key.
If Alt key doesn't work, then try pressing ESC as prefix

You should read Emacs tutorial at first
C-h t
M- is a simultaneous key prefix, for example, for M-x, you must
press Meta key and x key at same time.
In some situation, your keyboard doesn't support M-.
Then Richard Stallman figured out an ESC prefix to replace M-.
But in this case, ESC must be released, i.e., M-x becomes `ESC x'.
For C-M-x, you need to do `ESC C-x'.

Your keyboard is not standard.
ESC is a standard ASCII character, must be supported by standard keyboards.
