Hey, do you notice that you can access to all Safari shortcuts without searching from web?
It is inside your Safari. I will lead you to the file.
Enter the Safari
Go to Application folder and search for Safari tiny icon. on it and Show Package Contents.
Clck

Then following by opening these folders :
- Contents
- Resources
- English.lproj
- SafariHelp
- pgs2
Inside there you can find shcts.html. Open it to see all the Safari shortcuts.
Make It Simpler
Maybe you are too lazy to follow those path (as lazy as me). You can simply use your QuickSilver and type it all shcts.

And find the one with extension .html. Is it simpler?
Just Copy the Address
And I am sure there are some of you that do not want to waste time in searching this and that. Just use this link (your Safari Browser must be inside your Application folder).
Note : This is a local access, so you must copy link location and paste to your browser URL to open it. (You cannot just click it)
