This section of the General Preferences pane allows you to set some general options for
Drop Menu Delay:
Determines how long you must wait before the drop menu appears
when dragging to the Timeline, Layers list, or Canvas. The drop menu provides additional
choices for editing and importing objects into the project.
This checkbox turns tooltips on and off across the application. Tooltips
provide explanatory information such as names and basic usage techniques. They appear
when you pause the pointer over tools and controls.
