TAB key isn't bound to org-cycle with emacs on console

TAB key isn't bound to org-cycle with emacs on console

[Tassilo Horn]

Hello,

I use Org since about 2 month and I really enjoy it. Normally I use
GNU/Emacs with its X11 interface, but today I noticed that TAB is not
bound to `org-cycle' when I use emacs -nw or emacs in a login
shell. Then it's bound to the function I local-set-key it in
fundamental-mode-hook.

,----[ grep -A2 fundamental-mode-hook ~/.emacs ]
| (add-hook 'fundamental-mode-hook
|           (lambda ()
|             (local-set-key "\C-i" 'th-complete-or-indent)))
`----

When I do M-x org-cycle emacs echoes that I can run this function with
<tab>, too.

Does anyone suspect what could be the culprit?

BTW: I use Org-mode-4.64.

Bye,
Tassilo

First of all, not all terminal programs can distinguish between the TAB 
key and C-i - obviously yours cannot.  I am not sure if this can be 
fixed with som setup - you need to look into documentation on terminal 
windows for this.

If you cannot fix this,  you need to have org-cycle bound to C-i in 
order to get it executed by TAB.

The problem is that you do the above binding in a hook, and that you 
use local-set-key to do it.  Local-set-key defines the key in the 
current local map, which in org-mode is org-mode-map.  
Fundamental-mode-hook seems to be run (I did not know this!) when 
org-mode is started, because org-mode is derived from outline-mode, 
which is derived from text-mode which is derived from fundamental-mode, 
so all these hooks are run!

Here is what you can do:

1. Did you really intend to have this key binding in all modes, or did 
you only want it in fundamental mode?

If you only need it in, say, fundamental-mode and in text-mode, you 
could do

(define-key fundamental-mode-map "\C-i" th-......)
(define-key text-mode-map "\C-i" th-......)

2. If you really meant to have this in all modes except org-mode, you 
can make org-mode-hook (which runs after fundamental-mode-hook) to 
overrule this binding again.

(add-hook 'org-mode-hook
           (lambda ()
              (local-set-key "\C-i" 'th-complete-or-indent)))

3. You could make th-complete-or-indent smarter so that it calls 
org-cycle when you are in org-mode.


Hope this helps

Hm, I've tried the usual linux login shell, urxvt, xterm and
konsole. None of them seem to be capable of it, at least not with their
default settings.

Ok, no problem.

It was introduced yesterday and removed on RMS demand some hours
later. ;-)

Nevertheless, I've bound th-complete-or-indent in text-mode, too.

Well, I want to have them in all modes that don't use TAB for a
different purpose than indenting.

I guess you've meant org-cycle there, right?

Well, yes. But if I think about the whole function: I've written it,
because typing `dabbrev-expand' (M-/) is a pain on German keyboards and
I didn't want to lose indenting functionality with tab. But a while ago
I switched to a German Dvorak Typ II layout, where M-/ is easily
accessible. So I'll bint th-complete-or-indent to M-/ globally.
