This method does not require any third party software. However, it does require a keyboard with a num lock keys.
First you need to turn on the mouse keys in order for this method to work.
-Window Icon>Settings>Ease of Access>Mouse
- -Mouse keys>Use numeric keypad to move mouse around the screen (set to On)
or
-Control Panel>Ease of Access>Change how your mouse works
- -Control the mouse with the keyboard>Turn on Mouse Keys (mark the check box)
or
-just google it.
In the game, hover your cursor to a selected item you want to open or consume. Press “5” and “+” on your num lock keys at the same time and hold it. As a result, you should be opening items at a fast rate.
