Several spreadsheets are only 50 rows or so but CONTROL + END takes me to
cell H57459. The irritation is that the sliding bar on the right is a tiny
one and slight movements of the cursor on this bar along the screen result in
large jumps in rows. I have tried going to the END cell and DELETE-ing but
the same end cell prevails. How do I reset the END cell and, as a result,
regain a larger slide bar? Thank you.
