It's not a polygonal modeling tool ;)

So you must Separate or Copy Paste your selection for moving something !

Say you want Pull a face of a volume
Copy the face and move it
Loft the 2 faces
Boolean Union

Else all generic transformations are yet possible without Separate or Copy : Scale, Rotate

PS Only "Primitives" volumes have "Points" and no need to separate or copy!
So make "Show points" and you will can move vertices! ;)
So for move a segment of a primitive without separate or copy , you must move 2 points! ;)
