The feature commonly referenced is a device’s system clipboard. It is a temporary storage area where copied data, such as text or images, is held. Accessing its content within the Instagram application is indirect; Instagram does not provide a dedicated clipboard viewer or manager.
The system clipboard facilitates the transfer of information between different apps, including Instagram. Individuals often copy text or links from other sources, and then paste them into Instagram captions, comments, or direct messages. Utilizing this facilitates efficient content creation and sharing, bypassing the need for manual retyping.
