That was meant for a Mac, maybe useful to know before considering using a 3-button mouse - that’s why I posted this, but I agree this does not solve the esc-key issue you mentioned. Btw I’d suggest this post to be reclassed under the Layout rather than the SketchUp category.
The link I provided to the SketchUp help center gives more detail, quote:
On a one-button mouse: If you use Mac OS X, press and hold the Control and Command keys while clicking and holding the left mouse button.

I happen to play a bit of piano, maybe the reason why I am more receptive to keychords…
