Q: Keyboard shortcuts,

Why not just save it as a PDF.  Open the page, type Command + P and in the lower left click the box that say PDF - select Save as PDF and save it to wherever you would like.

No need... In the Finder:

• choose Help [menu]
• Mac Help (Command + ?)
• search keyboard shorcuts
• pick the result with most confidence
• voila!

You can also "customize them"

Your welcome, you can also save Mac keyboard shortcuts - Apple Support to your favorites. If you were used to using MS Windows keyboard shortcuts,  you will find them very similar. As a general rule, the only difference is PC use the Control key whereas Mac use the Command key. For example

Copy Command

PC = Control + C

Mac = Command + C
