In the editor view, double-clicking on a path will select it. You can also select a path by double-clicking on its row in the sidebar.
When a path is selected, it will be outlined in red, with a blue frame on some segments, and red control handles will appear around any draggable point. All control handles can be dragged around as you wish, and everything is automatically saved.
Double-clicking off of a path will deselect it, and hide all controls.
Control-Z and Control-Y work as undo and redo, respectively.
