Hi Brian,

> Wonder if the arrow keys on the keyboard can control the slider?

Right now there isn't anything set up for that, but that could be a good idea for the future.

It would probably involve some tweaks in control focus handling though - currently the system is set up to make it easy for any typed characters to be handled as input into the the first numeric input field that's present in the command UI, or on to the XYZ control if there isn't any edit field in the command UI.

That's why you can do something like run the Circle command and then just type 5 and push enter without actually needing to click on the radius field first before typing - when you type 5 the focus automatically goes to that field and puts the keystroke in there.
