where to place the keys and how many.

Spacemouse: image
You move the camera or the model with it. In all directions, with keyboard you can’t rotate all axis at once.

Now I wanna make it look like this:

But as you can imagine, the keys are in a bad placement. I don’t want that.

Probably not even that makes sense. I can only use my pinky for that. LOL.

I think it is very unnice if the keys are on the table. It’s hard to reach the keys in that case. I think the keys should be somewhere at the top of the spacemouse.

You have a lot of experience with how many keys you use often. I don’t know how many buttons i would need.

In my short time with zbrush here is my heatmap: https://i.imgur.com/pzrwZqI.png
y key is z key and vice versa. so roughly 100x ctrl for renew dynamesh and 100x for undo ctrl+y.

Do you also use the keys the most? Seems like 10 keys directly around the spacemouse should be enough.

How many keys do i need? (I think 10)
Where to place them for easiest access? ( I think the top of keys should be on same height as the top of the spacemouse.)
How to place the keys? Just in straight rows an columns or more diagonal like with the normal keyboard?

Well if nothing else I’ve just learned from this that Y is the shortcut to swap between Gizmo and Transpose, so thank you!
I’ve gotthe SpaceNavigator, and that has a couple of small buttons, one on either side. I’m sorry, I can’t see if yours does or not. If it does, are you wanting to use these too, or are you wanting everything to be on “keys”?
It might be a good idea to look at the current and historic 3D Connexion range, to see where they have founds to be effective to place buttons. Might give you some pointers?

Good luck with the project!!!
