The command "unclutter -idle ${3}" is a shell command that is used to remove the mouse cursor from the screen when it is idle for a specified amount of time.

Here is a breakdown of the command:

• "unclutter" is the name of the command/utility being executed.
• "-idle" is an option or flag provided to the "unclutter" command. It indicates that the command should consider the mouse cursor idle and hide it.
• "${3}" is a placeholder for a parameter or argument. In shell scripting, the symbol "$" followed by a number (such as ${3}) represents the value of a specific argument provided to the script or command. In this case, it suggests that the value of the third argument will be used to determine the idle time for hiding the cursor.

Overall, the command instructs the system to launch the "unclutter" command with the "-idle" option, considering the mouse cursor idle when it remains inactive for the time specified by the third argument.
