What mouse operations would you use if you want to draw a picture?

To draw a picture using a mouse, you would typically use the left mouse button to click and hold while dragging the mouse to create lines and shapes. Releasing the button would stop the drawing action. You might also use the right mouse button for additional functions, such as erasing or selecting tools, depending on the drawing software. Zooming in and out can be performed with the scroll wheel for finer details.
