The shift key thing is something I don’t think I would have ever found on my own. I came across it mentioned in this post: EstlCAM 12 on Linux - #7 by soup.
He mentions that behavior might be specific to his laptop a Lenovo ideapad and I’m using Lenovo thinkpads so there’s a chance it’s a lenovo thing but worth a shot either way.
That does bring me to one reason I’m tempted to try out kiri:moto though. I have a dedicated shop laptop and I like the fact that onshape is cloud based so it doesn’t matter what computer I’m using. I like the idea of using the kiri:moto plugin for onshape for that reason, but l don’t like the fact it uses stl files for flat stock.
