Can I manually edit the points along a path or curve in the blender UI? I create a curve or a path in Blender and can clearly see that it is defined by a set of points. What I want to do is manually edit the position of one of these points, instead of dragging it. That way I can ensure my curve / path is 100% accurate in terms of direction and length.

I am new to Blender and this community, so forgive me if this question is stupid. I have searched google, this site, and the blender manuals and have found nothing.

How can I do this in the Blender UI?

My properties menu looks like this:
In Edit mode, press N or click View -> Properties to open the properties panel. Then, under Transform you will have Control Point. This is the coordinates of the currently selected point. If you have several points selected, it will change to Median and editing the values, will move all selected points so that their median is located at the specified coordinates.

  

By Properties panel, I'm refering to the area that I marked with red edges in the image below. If it's not visible, you need to open it, either by pressing N or by clicking View -> Properties
