Everytime I watch my friends play dota I always wonder how they use dagger, BoT, or Guinsoo without clicking the item nor pressing the numberpad. With a little research and hours of googling and garenaing (lol) I found my answer!
Its the inventory A+ a 200kb file size, after you download the file you will see a H logo in the taskbar.
When playing dota just hold the alt+(coresponding letter) to use the key mapping, here’s an example pic I grabbed from www.tmsnetwork.org
To deactivate the key mapping program just right click the H logo and select exit.
