[C#/Interop] Setting focus on page just above footer

[Irr]

Hallo,

I'm fumbling around with C#, Interop and Word.
I'm wondering how I could set focus on the page so that the cursor is on the
line just above the footer, or the last line on the MainDocument?

Since I can't edit my own post, I would also like to find out how to search
for a certain text and add another line under it hehe.
