In v8, drawing a keepout rule, how to precisely move a point by entering a value rather than moving it with a mouse?
If I click a node and shift+M it always affect entire object.
I am also missing coordinates under Properties window, which could show object coordinates when entire keepout rule is clicked or individual when a node is selected.

A general table with all points for a rule area is not available (this could be a task for some python plugin). But you could move individual points to a defined position:
select the rule area → all handle points of that rule area are displayed
hover mouse pointer over one corner/midpoint → RMB-click -->context menu → Shape modification → Move corner/midpoint To…
If you need this command often: you could assign a hotkey to this command (filter hotkey list with “corner”)
