There are some instances where the Ctrl+End will not work in your worksheet. I cannot recollect an example and hence I have not posted about it. there are 2 ways to go in this direction.
1) Press Ctrl+Shift+End -->which will take you to last cell (bottom and extreme right) - however it would select the entire range.
2) Press Ctrl+Down Arrow then Press Ctrl+Right Arrow.
Ok...then try
Pressing END+HOME. Let me know if it works.
