Need a little help restoring prefferences.

Forum
macOS & Mac Apps

Hi all. i updated, and my Mac was reset to defaults. So I changed some prefferences to how I had them, but i'm lost on a few things. For instance, when I tap with two fingers ont he track pad, the doc should open. When I do, I hear this swishing sound, andmission control comes up. It's the double tap with two fingers gesture I'm doing, one i've always done inthe past. So can anyone help fix this? It's driving me crazy, lol. Also in safari prefferences, I have it set to read the page by dom order, but when I open the web, I see only about half the page. I'm sure this is something I did wrong, so if anyone who is good with prefferences canhelp, please do. Hope you could understand my explanations.
