If i understand you correctly, you want to insert increment numbers
into a column. I needed this every few weeks. Not often, but when
needed is rather tedious to do manually, so i've written a elisp to do
it once for all.
(defun insert-counter-column (n)
"Insert a sequence of integers vertically.
Example:
do this 1 times
do this 2 times
do this 3 times
...
If there are not enough existing lines after the cursor
when this function is called, it aborts at the last line.
See also: `kill-rectangle' and `string-rectangle'."
(interactive "nEnter the max integer: ")
(let ((i 1) colpos)
(setq colpos (- (point) (point-at-bol)))
(while (<= i n)
(insert (number-to-string i))
(next-line) (beginning-of-line) (forward-char colpos)
(setq i (1+ i))
)))
Use it together with buildin
kill-rectangle (C-x r k )
and string-rectangle (C-x r t)
or
query-replace (M-%).
Since from your example your increment is 4, and it's hex, you might
need to modify the code a bit.
