Setting fn key as Ctrl on Emacs

I am having difficulty in using Ctrl key on emacs. Because, fn key resides in the Ctrl key's location on my new keyboard.

What should I do to map fn开发者_C百科 to Ctrl on emacs?

I believe this is controlled by the variable ns-function-modifier, however, as I don't use a laptop I haven't had the opportunity to play around with it.

I guess that you should set it to something like:

(setq ns-function-modifier 'control)

There's a lovely new feature in EMACS 23 -- customize the group "ns" and you can set all the key mappings very conveniently.

The problem is not just for Emacs, but for the command line, too.

1. DoubleCommand. The solution I have been using for years is to install DoubleCommand. It is a free download and allows you to map any key to any other key. You do have to start it after logging out or shutting down, so I keep it on my Desktop.

2. MacOS Keyboard. In MacOS 13.1, They now allow you to map the function key to the control key. System Preferences > Keyboard > Keyboard Tab > Modifier Keys Button - and there it is.
