Selecting non-consecutive text in Safari text boxes?

I've been trying to find a way to highlight/select different ranges of text in Safari without luck; I know that selecting consecutive text can be done by holding down "shift", but is there any way to do it with non-consecutive text? TextEdit is able to do this -- I can select a word in one paragraph, hold down the "command" key, and then separately highlight a word or sentence in another paragraph.
