Delete button in my whitelist has disappeared!

Not sure what happened. Clicked delete, got a pull-down menu, inadvertently clicked something else … Bam! How do I get it back? Thanking you in advance for your help.

If you Control- or Right-click on a toolbar in Mac OS X, it will show a menu that lets you remove the button from the toolbar.

Choose Window > Customize Toolbar. You can also delete rules without using the toolbar by pressing the Delete key.

Thank you! So obvious … had I just used my noggin … but I went into panic mode.
