problems configuring company-mode for auto completion key banding

problems configuring company-mode for auto completion key banding

[Krishnakant]

Dear all,
I had used Emacs about 10 years back .
After that there were severl things due to which I could not continue 
using it.
However now I wish to use it for my python programming.
I am a blind user and I use emacspeak with emacs for all my activities.
I have tryed configuring company-mode with Python.
Basically I use elpy-mode which intern uses company-mode.
The problem is that although default auto completion behavior  is 
perfectly good for sighted users, for me it is too much speech.
So what I was trying to do is to set company-mode not to auto complete 
automatically.
I was trying to set C-tab for auto competion.

But it still auto completes which I just type 3 chars.

Here is my init.el file:
(require 'package)
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/"))
(add-to-list 'package-archives '("elpy" . 
"https://jorgenschaefer.github.io/packages/"))

(setq company-idle-delay nil)
;;(global-set-key [C-tab] (quote company-complete))
(global-set-key "C-tab" 'company-complete)
(global-set-key [f10] (quote python-mode))
;;(package-initialize)
;;(elpy-enable)



Note that I am very new to setting such things in Emacs.
So I have to manauly start python-mode when I open a .py file.  I am 
aware this is not correct but can't see what's wrong.
Would be happy if any one gives some tips or pointers or some example.
Happy hacking.

That's understandable. Since you are a blink user, though, I'm not sure 
if you can really benefit from the popup-like UI.

Maybe try and see if C-M-i works as well for you, and if it doesn't, 
request that elpy integrates with completion-at-point-functions.

The variable that controls it is company-idle-delay. Try:

(setq company-idle-delay nil)

You can find all the customization variables by typing 'M-x 
customize-group RET company'.

Emacs should enter python-mode by default in .py files. If it doesn't, 
what major mode does it use? You can find out by evaluating 
'major-mode'. Press M-: to evaluate an expression.

I can certainly use the dropdown because I choose from the list using 
arrow keys.  All I need is that it happens one only when I want it.

Where should I have it?
Should I put it just any where in my .init.el file?

I can't figure why either. Have you checked the variable auto-mode-alist?
It should contain the element ("\\.py\\'" . python-mode)
