how to enter this 2D math in Maple document mode?

I do not use input 2D math in document mode. But was trying it now to see if I can enter this to check my hand solution

In worksheet, this is what I do

restart;
VC:=VectorCalculus:
f:=y*sin(x)+y^2;
VC:-DotProduct(VC:-Del,VC:-Gradient(f,[x,y]))

But I do not know how to enter   if possible, in document mode 2D math. THis is what I tried. Created document mode. Picked the DEL operator from the left side common symbols window. But I do not know how to do the rest.

Clearly I am doing something silly. This is why I prefer plain Maple code, becuase I can see what I am typing :)

But was wondering, how to do the above in docuemnt mode + 2D math? To make it look close to how it shows in the book. Does one need special palette for this?
