    "* Then **click** on the **plus** icon that is revealed when hovering. This shows the query vectors, key vectors, and intermediate computations for the attention weights (<span style='color:blue'>blue</span>=positive, <span style='color:#ff6318'>orange</span>=negative).  \n",
    "* Once in the expanded view, **hover** over any other **token** on the left to see the associated attention computations.\n",
