# Change multiple custom properties simultaneously

When I ⌥ Alt LMB on a transformations property, I can change multiple the property for multiple object with once input action. The property turns blue for the duration of the operation.

Is there a way to make this work for custom properties?

• While it is possible to use "Alt"+LMB on values like rotation, you can also use the right-click menu and "Copy to selected" or it's variations like "Copy to all selected" and "Copy single to selected" while the first is easy to understand the latter i didn't yet figure out the difference of. That said, the custom property value does not have that option of "Copy to selected", thus i believe there is a differentiation inside Blender that may as well be reason why the "Alt"+LMB combination is not working there. – Xylvier Nov 20 '19 at 16:36

• They are the same regarding the possibility of different objects having them or not. That may not be the reason you can't mass edit them with Alt key, probably just that the properties are not "the same" despite sharing a name. – Duarte Farrajota Ramos Nov 30 '20 at 18:34
