orbit the selected object

[kame]

How can I orbit the selected object not by using mouse but by using keyboard ?

Howdy kame,

Press and hold the Shift key, then use the arrow keys.

The rate at which you orbit the object can be controlled by changing the RotateAcceleration value in celestia.cfg, which is located in the main Celestia directory / folder. The default value is 120.0. Use a lower value to orbit slower, or a higher value to orbit faster. After changing this value, you need to re-start Celestia.

Does this help?

Thank you Don for your reply.

I am afraid I do not want to rotate but want to revolve around the selected object.

When we click right and drag Mouse, we can revolve around the selected object(ex Earth ,Mars,‥‥）.

I want to do this by using Keyboard.

Is it possible?

Kame,

I think perhaps you misread what Don wrote.

Typing an arrow key without holding down a shift key causes your viewpoint to rotate around one of its own axes.

Typing an arrow key while holding down a shift key causes your viewpoint to revolve (orbit) around the currently selected object. This seems to be what you are asking for.

Thank you Don and selden.

I can do it ！

I used Celestia 1 2 4. It might be problem.
Now I downloaded Celestia 1 3 2.
It works as you told.

Thank you very much！
