Collaboration and Editing in Google Forms

Watch How to Use the Collaboration and Editing in Google Forms:

Now with collaboration 
Create a form faster than ever. Just as with Docs, Sheets and Slides, you can now collaborate with others in real-time. If you need to work with two colleagues on a survey, all three of you can work on the same form simultaneously and even have a group chat on the side, without leaving the form.

Better editing 
Even if you’re working solo, some new changes will make creating and editing forms easier. All your changes are auto-saved and you can quickly undo/redo edits. Improved copy-and-paste will let you copy a list of bullets from the web or multiple rows of text from a spreadsheet; then, when you paste into a form, each line will be appear as an individual answer. And you can use keyboard shortcuts to get things done more quickly.
