For regular ellipses and rectangles you can press the space bar to assure a true sphere or square; this does not work on other shapes.
I have shape just created that when placed, regardless of the size I want to maintain the vertical and horizontal ratio. I see nothing in the documentation, but it would be very useful to lock the ratio; it is too easy to squash or elongate a shape.
It would be good to have some key combo (or - orthogonally speaking - the space bar) that will maintain any shape ratio.
Thanks so much for this tool.

Pressing and holding the Shift key should get you the result you’re looking for — this actually constrains proportions pretty much everywhere in the app (and in most other apps, including when you’re resizing macOS application windows). However, there is a trick to it, which is that you have to press the Shift key after you begin drawing a shape because the modifier keys can also be used to unite, subtract, intersect, and exclude shapes. Also, pressing and holding the Option key (after beginning to draw a shape) will increase its size from the center in all directions, rather than from one corner, which you might find useful.
