Layers and groups
Select overlapping elements and control what appears in front.
Find an element in Layers
Open Layers for the selected slide. The tree shows groups and their children. Click a row to select its element on the canvas, including elements hidden behind another object.
Change stacking order
Use the layer actions in the selection menu to bring an element forward or send it backward. The [ and ] keys move it one level; Cmd/Ctrl + [ or ] sends it to the back or front.
Lock an element from the selection toolbar to avoid moving, resizing or deleting it accidentally. Unlock it to edit it again.
