First, we open the PPT courseware, then click the slide in the menu bar and choose to start from scratch. Then we can play the slides. If you want to mark in PPT, use the right mouse button to select the pointer option-pen, and you can mark on the slide at will. Just like chalk, you can switch different colors by clicking on the ink color. The role of the laser pointer is that an obvious red dot will appear and shoot on the slide, but it can only be used for instruction movement; Highlighter can also be used for marking, such as smearing a key point; There is also an eraser function, which can erase handwriting.
