 *      pressTab                - Simulates an Tab Arrow button tap
 *                              - Example: pressTab(); 
 *      pressEnter              - Simulates an Enter button tap
 *                              - Example: pressEnter();
 *      pressDown               - Simulates an Down Arrow button tap

 *                              - Example: pressUp(); 
 *      pressGenericButton      - Function for undescribed keys. find more on: https://github.com/octalmage/robotjs/wiki/Syntax 
 *                              - Example: pressGenericButton("home");
 *      mousePosition           - sets the mouse pointer to the X Y location instantly
 *                              - Example: mousePosition(250,250);    
 *      mouseMove               - moves the mouse humanlike to the X Y location
 *                              - Example: mouseMove(250,250);  
 *      getPixelColor           - returns pixel color of mouse location
 *                              - Example: getPixelColor(250,250);
 *      downloadChromeFile      - Simulates a user filling out a chrome download prompt, use in promise
