When we marquee a selection and hit Escape — it gets canceled.
When we hit Escape while dragging out a guide — it gets canceled.
Dragging out a brush on the canvas — works.
Dragging out a swatch to drop it on a gradient or the canvas — works.
Dragging the appearance form the Appearance panel — works.
...and many other cases

Escape does NOT work for these cases:
1. Creating a shape, an artboard, an area text
2. Rotating, scaling, shearing, free transforming...
3. Setting up the width with the Width tool
4. Setting up the gradient with the Gradient tool
5. Building a shape with the Shape Builder tool
6. Using the Eyedropper
...and many other cases

Hitting Escape while moving an artboard commits it!

Can we get Escape to cancel anything we make/control/edit by dragging?
