You don't need to read all the documentation to get started!
Just remember that SHIFT is responsible for filters, and STRL is responsible for filter shapes...
That is, if you hold down the SHIFT key on your keyboard, you can create filters with the left mouse button, move filters with the middle mouse button, and delete them with the right mouse button.
And if you hold down the STRL key on your keyboard, you can do the same with filter points.
