Hi @radjesth !
The latest code is hosted there: https://flows.nodered.org/flow/7fb5bc5ae66e6bc1b1c1b8e800bdef51
It should be centered. Let me know if that works for you! Otherwise if I understand you, the keypad is centered horizontally but not vertically?

Dear Hugo,
Thank you for your reply.
I have another challenge.
I am using the numeric keypad.
As soon as you press a key, you can see the number in the upper place of the keypad.
I want it to change into a * after 500ms.
So, as soon as you press a number, it will show the number and then change into a *.
I don't know where to begin.
I have managed to change the font size and I have added a return key, but this is not my cup of tea.
Your help would be appreciated.
Kind regards
I am trying to use the latest virtual keyboard to feed a text input box. I notice that as I touch the buttons in virtual keyboard the individual letters are being sent from the text input node and not waiting for the close box. The text input has a delay setting 0 which waits for an enter key to send the payload. This works as it should using the keyboard. Here is the sequence of events when pressing 123 and then pressing the close box on the virtual keyboard:
press 1
msg.payload = ''
press 2
msg.payload = "1"
press 3
msg.payload = "12"
press close box (x)
msg.payload = "123"
I can live with this for data entry because it just overwrites, but I have some inputs that trigger an action when you press the enter key. Any suggestions on how to change the code to fix this?
Thanks,
Tom
I am seeing this behaviour too. Not sure where/what is causing it. In my case, I enter a qty of something (eggs layed if you must ask 
) but the message is passed as described here. Entering 20 sends 2 then 0. I'll report back if I find what causes this.
Hi @tcr000 and @mfassier
Happy new year, sorry for the long time for my reply!
Please send a flow example so I can reproduce, when I try a number box with delay 0, I don't see the behavior you describe.
And to you as well 
So, here's my own example:

Now, on this, when I click the field, the vkeyboard shows up and then I type 1, 2, 3, enter. The output is
That's not the desired outcome, as the input node should wait to have the full "123" message and wait for the "enter" to pass it along. To be clear, this may be an input node issue, but the odd thing is that this used to work in a not so distant past, say 6 or 8 months ago. I can't pinpoint a change that would explain it.
Hope this helps.

Hi @mfassier ! Here's a quick modification of the vKeyboard script that should only send numbers after a "return" click. Let me know if it works well for you!
<script>
// the semi-colon before function invocation is a safety net against concatenated
// scripts and/or other plugins which may not be closed properly.
; (function ($, window, document, undefined) {
// undefined is used here as the undefined global variable in ECMAScript 3 is
// mutable (ie. it can be changed by someone else). undefined isn't really being
// passed in so we can ensure the value of it is truly undefined. In ES5, undefined
// can no longer be modified.
// window and document are passed through as local variable rather than global
// as this (slightly) quickens the resolution process and can be more efficiently
// minified (especially when both are regularly referenced in your plugin).
// Create the defaults once
