Quote in gmail web interface?

Question

gmail

Hello everyone
Tell me, no one solved the problem of quoting in the Gmail web interface - conditionally, the letter is large, I first read it - I select the text that I want to comment on, and it is added to the response form.
Now you have to copy a block of text, go down - paste it - select it and press quote.

Quote selected text when replying to an email. (Now you can use your mouse!)
I hope it helps you

Answer 2

What is the difficulty?
In the response form, there is an ellipsis behind which the quoted text (the entire text of the letter) is hidden.
In it, you answer and comment on the necessary pieces. The rest is either deleted or not.
