Source mode tends to be infinitely easier than Visual Mode once you know how it works, so I'll gladly tell you. You see, in the "my preferences" thing (You'll find it here), you just gotta head to the "Editing" tab you can change your preferred editor. You can switch from Visual, Classic, or Source. You can switch between the three at any time when you go to that tab.

I hope this helps. Feel free to inform me of any issues you encounter. I recommend experimenting with the options you can use in Source Mode to get the hang of it.
