text box manipulation with text boxes

Essentially, I have 7 different check boxes and 1 text box. Using Javascript, is it possible for me to manipulate what is written in the text box based off which check boxes are checked? (i.e. if check box 1 is checked, then the text in the text box should read "check 1", if check boxes 2 and 5 are checked, then the text in the text box should read "check 2 and 5", etc.)

Please help!
