How can I manually set the numeric values of coordinates of nodes on a path or object?

Hello:

I am totally new to CorelDRAW.

I could not find a way to precisely set the coordinates of a point on a path. Consulting the manual, I became confused. When I select the path or any closed object, I see a list of all coordinates in the Coordinates Inspector, and the point I click on with the node selection tool is highlighted. However, for the life of me, I could not enter a new value for the point, and all I ended up doing was creating new points.

Could someone kindly direct me as to how to accomplish this? I am perplexed, having not run into difficulty with such as basic function in other vector design programs. Thank you very much.
