I'm a absolute beginner to Blender and I don't know how to move the vertices. I only have a one-click mouse. I tried to see others comment but no use. The B key doesn't work for my computer.
When you have selected a vertex, press G to move it. But in your case I'm not sure you going to come far with a 1-click-mouse. In addition it's a good idea to read the blender documentation or watch some tutorials about blender on YouTube to get an idea of what you are doing.
