Then the position box on the bottom will be unlocked and the vertex you've clicked is the reference for position values
Although I didn't knew that feature that's not what at least I was talking about. This way the relative distances between the vertices remains fixed. I want to first select an arbitrary number of vertices and then set their x, y and z positions. When setting these coordinates all selected vertices should get the same values and not remain on their relative distances. The result would be the same as first merging those vertices and then move the merged one around - just without the merging... ^^
