So I want to add assumptions in carrying out integration. I know I could use the Integrate function:

Integrate[V Exp[-x/a] ,{x,0,10}, Assumptions->a>0]

but this gets very tedious when I could just use the shortcut

esc + dintt + esc

in the case of a definite integral. Is there any way to specify assumptions using shortcut functions like this, or does one HAVE to use the Integrate function?

The AddInputAlias function in the Notation package solves this problem. To use the example input alias created below, simply type Esc apply Esc.

<< Notation`;
    RowBox[{"\[Placeholder]", " ", OverscriptBox["\[LongRightArrow]", 
    RowBox[{" ", "Apply", " "}]], " ", "\[Placeholder]", " "}]], "apply"]
