Showing all hidden components in assembly

Hello!

I am beginner in Solidworks and I was looking for command which causes showing all hidden components in an assembly.

I found (at forums) that "Show with dependents" is very helpful.

How could I make a shortcut at my toolbar for this command?

I can't find the icon at "Customize" option.

It is only at "Menus" but I can't deal with it.

What is it "Name of command" (third row below table).

Sorry for my english.

Please for help,

BR
