It is the partial derivative with respect to the first variable (a).

y = Hypergeometric1F1[a, b, z];

D[y, a]

\!\(\*
  RowBox[{
    SuperscriptBox["Hypergeometric1F1", 
      TagBox[\((1, 0, 0)\),
        Derivative],
      MultilineFunction->None], "[", \(a, b, z\), "]"}]\)

Use FullForm to see this more clearly.

FullForm[%]

Derivative[1, 0, 0][Hypergeometric1F1][a, b, z]
