6. The Tools in the Toolbox / 6.2 Tools for All Kind of Layers
Curve Creation is a mix between vector graphics creation and editing. It can be used to create new paths, but already entered points can be selected and edited, too.
By clicking and dragging new curve points are created, simple clicking creates line points. Because you can't create a line point directly after a curve point, you can force to create one by holding Shift.
By holding Ctrl (Windows) or Command (macOS) a new vector layer will be created. Holding Shift+Ctrl/Command will create a new subpath in the active vector layer.
Close Path in the Tool Settings controls, whether a new path will be closed automatically or whether it will be open. If it isn't closed automatically, you can close it manually, too.
If you double click an already selected vector point, its position can be modified numerically.
Editing points works the same way as in Edit Vector Points (see chapter 6.4.1).
