Well worth the $ // Excel Laminated Shortcut Card
This is exactly what you would expect from looking at the picture. It's a 2-sided laminated sheet of paper with a ton of excel shortcuts printed out. Exceljet offers a similar product for free on their website, it's a PDF manual of 200 shortcuts. I started with that & ended up buying this as well, as it is so convenient to hang on the wall next to my computer for reference. The PDF manual is great too, but this is just faster to use. Well worth the $ in my opinion. - Mark
