how to change name and command of icon in desktop?

[San Segkhoonthod <sans webzone net>]

I created new launcher in my desktop: entered name,command, and changes
type to "Application".  Then, I wanted to change name and command, but I
couldn't?  I clicked on its properties but I didn't see a way to do
that.

Is it be design? or is there a way to do that?
