Diagram for teaching Shortcuts in Excel

Please See Attachment I teach Microsoft Office Applications, including Excel. In Excel, using Shortcuts to perform tasks is a real time-saver and sets the difference between an average user and a professional. However, Shortcuts are difficult to remember (if you do not use them regularly. That is why I created different techniques of memorizing the shortcuts: Alphabetic, By Numbers, By Function keys. When I created this system, I created it in a “Table” format. But I would like to make it more (much more) graphical. So my project is to split the single tabular design into 3 separate Graphic designs: 1- Alphabetic Shortcuts (A to Z) using the CTRL key. 2- Numeric Shortcuts: a- CTRL + any number (from 1-9)  Text Formatting b- CTRL + SHIFT + Any number (from 1-9) Number Formatting 3- Function Shortcuts: using the F1, F2, F3… keys
