Turn off autocomplete in the App Script editor [duplicate]

Any idea how to switch off the contextual help that covers your code above the line you are working on? It also covers the auto-complete which is super annoying.
There is no user preference setting to disable contextual help in the new Apps Script code editor.

New Apps Script IDE too helpful. Can you turn it off?

How to get the DOM elements of the active page in google app script from add-on

I am currently developing a google calendar add on . And I need to access the DOM of the current active page from the add On
I need to know how to get the DOM element in app script for google add on
Problem
Unfortunately, at the day of this answer there is no functionality in Apps Script to get the DOM of any site.
Workaround
Try using a chrome addon as these might let you get the DOM of sites. Here you can find out more about chrome add ons.
I hope this has helped you. Let me know if you need anything else or if you did not understood something. :)

Google Chrome extension - integrate with Google Calendar

How can a Chrome extension alter the Google Calendar event editing UI?
I see that, for example, the Moxtra extension has managed to inject UI including a button just below the location. According to their YouTube video they added a button to fill out the event description although when I installed Moxtra this no longer seems to work.
Stepping back from this a bit, it occurs to me that editing the Google Calendar page seems like something that could easily get messed up by future changes to Google Calendar. Perhaps it is better to edit the event description from the extension's own UI? If so, how can that be done?
Thanks.
It can be done with content scripts and modification of the DOM.
They probably check Event edit page for specific selectors and try to insert their own elements in the page, if they found it.
So, if UI of Google Calendar will change, extensions like Moxtra will be probably also broken.
You are right about the edit of the description - it's safer. But you still need to get a description field and change a content of it. There is no 100% safe way to do it and don't break on the change of UI.

how do i see code behind the Google sheet add on?

I created couple of google sheets add on, but then later my associated google account was disabled and can't access/edit those add ons.
Instead of starting from scratch I thought to ask here if there is a way to see the code behind the Google sheet add on?
thank you
No such API to view source code for Add-ons, nothing mentioned in the docs atleast.
