What is a Marquee in design software?

A marquee in design software refers to a selection tool that is often represented as a dotted or dashed line drawn around an object or area that a user wants to manipulate or edit. This rectangle allows designers to define a specific portion of their design for actions such as moving, copying, deleting, or applying effects. The ability to create a marquee selection helps streamline the design process by letting users focus on particular elements rather than the whole canvas.

The other options refer to different functionalities that do not relate to the concept of a marquee. For instance, managing palettes pertains to controlling color selections and swatches, saving documents involves file management, and adjusting opacity pertains to changing the transparency of an object, none of which involve the selection process represented by a marquee.
