I'm using the "lasso" selection tool by holding Ctrl and dragging the left mouse button in edit mode in order to select a group of vertices inside the selected area. However, my mouse hand isn't very good at drawing straight lines, and I keep selecting vertices that I don't want. I can select like the top shape, but need to select in straight lines like the bottom shape:
Is there such a thing as a "straight lasso" select tool, instead of the freehand one? I've tried using the B keyboard shortcut to select in a square, but I need to be able to draw my own polygonal shape.
