Take a look at the 'SyntaxEditor.SelectedView.Selection' class. It provides many properties and method for adjusting position. Typically, you want to use Offsets in SyntaxEditor (which is an index starting from the beginning of the document). I believe the Document Lines collection (can't recall where it's located) will allow you to find a particular line and get the starting offset of that line. YOu would then add 26 to the starting offset to get the offset for column 27.
It was initially difficult for me to adjust to using offset, but it's proven to be a very good implementation.
