All of the "video-type" software application programs I have used before were set up where you had to find the lesson title that you thought MIGHT have the exact procedure you were trying to learn how to accomplish. I watched a lot of stuff that did not stick in my mind because it was not related to the problem at hand; but I had to stay tuned because my procedure might be the very next thing the instructor was going to cover. This made for a lot of wasted time as well.
However, in Power Excel with MrExcel, there is a search feature that you can use to zero in on the exact thing you want to learn. Just type your search term into the box, hit enter, and a list of lessons will appear that relate to your search. Click on the one that seems a best fit, and Shazam!, you're watching MrExcel point, click and explain how to do what you need to learn.
