Hi,

Essentially, I am looking for a way to place large vertical bar inside the
equation (using WORD2007 equation editor). The aim to use it when typing
definite integrals i.e. you type the solution to the indefinite integral,
place vertical bar and then specify the limits of integration.

I was trying to change the size of the normal vertical bar inside equation
but it changes the size of the whole equation. So, additionally, if anyone
could suggest the way to change selectively the size of symbols inside
equation, it would be great.
