Edits on selected rows

Any edit on a selected row — a value, checkbox, dropdown, colour, texture, Light Group, key, name, type or on/off — applies to every selected light you can see. An edit on a row that isn’t selected changes only that light.

Undo

Every edit made in the panel is one undo step: Ctrl+Z (⌘Z on macOS). A slider drag is one step however long it lasts. The Global Preview controls (Wireframe, Illumination Adjustment) are not recorded for undo.
