Please see also the page http://www.emacswiki.org/emacs/AltGrKey for
how to type C-M-\.

Emacs Devel: Could we please get this information into the manual? I
think it fits under (info "(emacs) Windows Keyboard") where AltGr is
mentioned.

C-x h M-x indent-region RET

I have bound `indent-region' to <f5>.

All those commands are unusable anyway for they're to difficult to type.
But four of those come with easier to type alternatives, which are not
mentioned there. Why?

C-M-@     =>   C-M-SPC
C-@       =>   C-SPC
C-x C-@   =>   C-x C-SPC
C-x r C-@ =>   C-x r SPC


Only backslash commands might be problem. They are not on none of my
(German) keyboards. I guess it's a problem of the underlying system
(Windows I guess). How about filing a bug report there?

Those commands are:

  `indent-region' has to be rebound (<f5> here).
  `set-input-method'
  `abort-recursive-edit'




I think http://www.emacswiki.org/emacs/AltGrKey is obsolete and should
be fixed.

That is a good observation.

Why? 
TAB does `indent-region' just fine

Since no one answered I am doing that right now.

Only with Transient Mark Mode.

I have rewritten the wiki page. There are now also a summary of
problematic key bindings (which I think should be fixed).

Comments and critique is (almost) welcome.

i.e. by default.

Well, either `indent-region' is important enough, even in the presence of
TAB/TMM, to get a keybinding (currently C-M-\), in which case it's
worthwhile to consider whether certain keyboards have difficulty
generating that event, or it's not, in which case we can just get rid of
the keybinding altogether now that TMM is the default and have one more
available for user customization (for those users on whose keyboards it is
a convenient chord).  Saying "it's a bad keybinding but we really don't
want it anyway" strikes me as nonsensical.

I agree. Let us get rid of C-M-\.

And I think we should get rid of the other troublesome keybindings
too, see http://www.emacswiki.org/emacs/AltGrKey where I have listed
those now.

If some of them are important (and I think some of them are) they
should get new key bindings.

C-M-\ was there before t-m-m was the default.
t-m-m by default just made the binding not as useful as it used to be by
default, but people might still be using it.

TAB is a simple solution, it works by default.
We cannot provide generic solutions for all non-default options.

I have not said or implied anything of the sort.

Sorry, I was into something else.

I saw you added more of these `impossible-to-type' keys. I've thought of
switching the keyboard layout to neo2 already :-)

Thank's for the update.
