Changing the settings in Gnome

Does anyone know of a way for me to change the setting where when I put my mouse cursor in the top left it opens the activities bar, I would rather just be able to do that by hitting the windows key (not sure what to call it outside of windows lol).
Also, getting rid if the notifications bar would be nice :) maybe I could bind that to a key as well?

Thanks a bunch.

You have to open system settings, go to keyboard and then shortcuts, in settings you find the activity tray shortcut and you can change it as you prefer :)

There is an extension that can disable the top left hot corner, just dig around and you'll probably find it.

Also, the windows key is commonly referred to as "superkey"
