The “Y” command also supports the value increment/decrement of any command
using the ‘+’ or ‘-‘ signs as the third parameter of the “Y” command.
For example, move the PiP window one step to the left
Send: “#Y 0,141,-,1<CR>”
Reply: “~01@Y 0,141,-,1 OK”
For example, in order to increase zoom on the main window
Send: “#Y 0,650,+,0<CR>”
Reply: “~01@Y 0,650,+,0 OK”
