[Javascript] Click on link to generate text in a textarea?

[David Yee]

Hi all.  Is it possible to write javascript that'll automatically 
type in text in a <textarea> when you click on the link?  E.g. I have 
a link called COMPANY_NAME, and when I click on the link I want the 
text "My Company" to be typed in immediately into the <textarea> box 
next to that link at the cursor (thus not destroying what's already 
in the text box).  Thanks for any help!
