I am new to Synfig and just going through the tutorial on animating a character. In the video the person is able to change the center of a layer i.e. the green handle, in order to rotate the hand without having to manually adjust it. He does it with CTRL + dragging the handle to where it should be. It doesnt work for me, unfortunately, as the layer moves with the handle. I checked everything, including trying to use an on-screen keyboard, but I failed. Any suggestions? The software version is 1.40 on Windows 64. Thank you !
