I have BUG installed. I saw some of Quill18's let's plays on youtube, where he did a variety of utility things, like plant markers (the type I remember seeing in the World Creator) leaving notes of what improvements he's going to make onto a tile, planting grey BFCs where he wants to plant cities, and even drawing red lines to show other types of boundaries. I can't seem to figure out the keyboard input for these types of notes? How do I get them? The BUG download didn't come with a PDF instruction manual, so I'm having to figure this all out on my own!
