Adding an in-text citation from within Word (will also update your reference list)
First highlight your desired reference in EndNote by clicking on it once..
Change across to Word (you can use the keyboard shortcut Alt+Tab or click in the Windows taskbar to change programs)
Click once with your cursor in the Word document where you want the reference to be inserted.
In Word 2007, select the EndNote tab on the "ribbon", and in the Citations group, click on Insert Citation then Insert Selected Citation(s).
In Word 2003, position the cursor where you wish to insert the citation, and select the Tools menu, EndNote, and Insert Selected Citation.
Changing back to Word, you should see both the in-text citation and the entry in your reference list have been added automatically.
