How do I move between desktop spaces?

solved
question:

1. how do I move between windows on a mac?
2. how do I move between desktops on a mac?
3. what's an alternative to the three finger sweep to change desktops on a mac?

And the answer is:

to move between "desktop spaces" on a mac, you can do it three ways:

1. four fingers up on the trackpad, then choose the desktop space/window/desktop/whatever you want
2. three finger sweep to go between spaces/windows/desktops
3. control -->      That is, hold down the control key and use the left or right arrow on your keyboard
