The remote PC cursor on the smartphone screen is moved with a finger. Instead of clicking the left mouse button, quickly tap the display once.
A long press is used instead of a right-click.
To zoom in, place two fingers in the middle of the display and drag them in different directions.
If you want to open the program menu, swipe your finger across the screen from left to right.
If you need to type text, click on the keyboard image in the menu. Immediately after that, a touch input panel will appear below the broadcast window.
