Always wanted to know....

...but kind of too nervous to ask. You know the sort of thing.

I should like to know how to do that thing, where you write to someone offering them a link, but instead of typing in the link, offer it as a word in the text which provides the link when they 'ding' on it. I do apologise for asking what might be an annoying/simplistic/everybody except me knows this type of question.
PS. I am blonde...
