240. You can refine later.

Let's say you can't even count the lines!

You can always, and only with emacs, type:

M-: (forward-char (/ (- (progn (end-of-line) (point)) (progn 
(beginning-of-line) (point))) 2)) RET

Well, C-f C-n is all you need.  I mean, keep C-f pressed until the
cursor reaches the column you want, you don't even need to count
76.  And keep C-n pressed until the cursor reaches the line you want.

WFM.  So far.
