Help Red curser circle thing

[Joan006]

Sorry this sounds ridiculous, but when I'm typing a message and i mess up and try to place my curser somewhere close to the mistake to correct it, what does the red circles mean/do?
Is there an auto correct thing i'm not understanding?
Thanks for helping!

If we are thinking of the same thing, clicking (tapping) and holding on the red circle will bring up a small screen that is zoomed in on where you are touching.

This allows you to carefully move the cursor where you are trying to edit. For instance, if you wanted to remove a letter 5 words back, instead of attempting to tap right to where you want to delete the letter, you can tap once, then hold on the red circle for a little more accuracy
