how to reach the usual “alt-…” keyboard bindings with an emacs from emacsformacosx

• http://emacsformacosx.com =  “GNU Emacs For Mac OS X” – this is the emacs, I am referring to here.

OS X and emacs use the “alt” key differently, so how do I achieve on OS X within emacs what I usually achieve with “alt“, like entering “[” through alt-5?

I sacrificed the right “alt” key to work the Mac OS X way (by setting ns-right-alternate-modifier to none), and the left “alt” key to work the emacs way.

Enter this within your emacs (from emacsformacosx.com) on OS X:

M-x customize-group ns

“ns” is the customization group for “GNUstep/Mac OS X specific features”.

• http://stackoverflow.com/questions/10978598/osx-option-alt-as-meta-is-there-a-way-to-port-or-use-emulate-mac-keyboard-mode

Now I can enter “[” on my Austrian/German Mac keyboard through (right) alt-5.

I had waited far to long, before thoroughly investigating this.
