e.g. I want to change the positions x, y, z of an object from 0,0,0 to 10,10,10. Although they have the same value, 10, I need to type them one by one on Transform panel.

Is it possible to select them together by adding them into one selection? Just like we hold down ‘Shift’ key to add objects into the selection.

Thank you very much.

However, this method doesn’t work in other areas such as parameters inside kinematics. Is there any method to select multiple parameters except only on the Transform panel?

That’s the only way. However if you know that you are always going to want certain values to be equal, you can drag the animation icon from one onto the others to create = expressions. That way, you only need to set one value.

Set your parameters keyable.

Then, use the keying panel.  With it, you can multi-select the sliders and type in a value to set them all to the same value. Just like with the channel box in Maya

Drag-and-slide, or ctrl-click the right part of the keying panel, where the sliders are, then type in the value.
