What is the keyboard shortcut to select all objects in a document?

The keyboard shortcut to select all objects in a document is Ctrl + A (Cmd + A on Mac). This command is a commonly used shortcut across various software applications, making it intuitive for users to select everything in their workspace quickly. In Adobe Illustrator, using this shortcut is essential for efficient workflow, especially when working with multiple objects or layers.

The other options do not correspond to the function of selecting all. Ctrl + S (Cmd + S on Mac) is commonly used for saving documents, while Shift + A and Alt + A do not have any default functions related to selecting all objects in Illustrator. By utilizing Ctrl + A (or Cmd + A), users can avoid the time-consuming process of clicking and dragging over items or selecting them individually, allowing for more streamlined editing and manipulation of artwork.
