I found the shortcuts very useful and I like to use them all the time, And I like the shortcut sheet you created but I have two suggestions for you regarding the shortcut sheet:
1- If you can add new column called mode and in that column we can see if the shortcut worked on the edit or object mode,
2- If you can add it to google drive and share the link so you can modify it at any time and we can get access to the latest version without download it again.
Thank you for your great work, I am watching the first 3 section of this course for the 2nd time and still learning a lot.
