Mousercise Day 2 step Q3 Keyboard Shortcuts Help and Undo

Extra Credit Mousercise- Day 2, Step Q3 - Keyboard Shortcuts
After opening various menus, you may note that there are letters to the right of many commands. These are the keyboard shortcuts that will get you to these options without using the mouse. Many of these are standard, and will work in almost all programs- so they are very handy to know.
Help will get you to written instructions that you may browse through - or search for key terms. F1 on the top row next to Esc will bring up a Help for whatever program is being used.	Undo will take a step backward. Sometimes you don't know what you leaned on to make the mess- so it is difficult to figure out how to return. Hold Ctrl and tap the Z to take a step back.
