We could do it dy dx. Or, maybe we will want to actually make a change of variables to first shift this to the origin, x-2 you know, change x to x minus two and then switch to polar coordinates.

也可以dy，dx来划分，或者,对变量做一下变化，移动到原点，就是把x变成,然后再转化成极坐标。

If you have a really large project, with hundreds of clips, pressing (and holding) shift will present a zoomed-out view, where each pad now represents an 8 x 8 section of a project, letting you quickly jump about to different parts of the session.
