how to change user preference in blender version 2.81 i just downloaded blender 2.81. I'm very new to blender. I'm using blender on a laptop and I know that some settings are different if you don't have a mouse (which I don't.) I've learnt online that you're supposed to change the user preferences. From what I've read, you should type %appdata% in the windows search box and find the app data file (which I did), and i did find the user preference window  (userpref.blend) thing. Problem is, I don't know how to change the user preference after I've gotten into the window. Can someone kindly tell me what I should do next? thanks!
The preferences can be edited within Blender. For 2.8x they are located in Edit > Preferences. More information can be found in the manual.
