| : With the game stopped at a breakpoint, hover the mouse over a variable in the code editor to see its current value. Simple values show directly in the tooltip. Tables open as an expandable tree that you can navigate, and each row has a copy button that copies the value to the clipboard. Hovering a dotted expression such as `self.position.y` shows the value of the full expression. |

Because this docs repo rebuilds the public Defold site on push, this paragraph would advertise a debugger hover feature to all readers even though the referenced implementation PR (defold/defold#12920) is still open against defold:dev as of August 9, 2026. Until that editor change is merged and available in a release/beta channel, users following the manual with the current editor will not get variable-value tooltips, so this should either wait or clearly state the required editor version/channel.
