Find my JavaScript keypad solution in the attached file. Please do give me better suggestions/solution if you don't mind.

I included JavaScript code and commented some other code in the /public_html/components/com_ariquiz/assets/js/questions.js file for method AQ.questions.FreeTextQuestion draw function
and then I also added JavaScript functions to the head tag in my template's index.php

Although it is working from there I am not sure if it is the proper place to add the code to the template's index.php head tag.
Any replies on this?

Some adverse events:
* when typing the answer after question loaded without setting focus with cursor in the answer tab it is working perfectly on my laptop and Samsung 10" tablet,
- but on my mobile phone Huawei P8 lite it is typing double digits.
- On my son's 7" Lenovo tablet it gives error when I tap on the Enter to load next question. (maybe something wrong with my JavaScript)
See the quiz on speedskillsonline dot com www.speedskillsonline.com

Since some mobile devices and tablets caused double entries when keyboard numbers are pressed, I modified the js code to accommodate for that as well.
See the new zip attachment.
Is there a beter place rather to put the js code part in the header of the template?

Can you send it to me as well?
I will be very thankful

I belief this is my latest version
See attached.

Thank you very much... It works perfectly on my laptop...

Did you apply it to MultipleFreeTextQuestions as well?
