There are several easy ways to change the name of your binder, which is also the subject line of your alert.
Click the binder name at the top of the page to edit it. Type enter to commit.
Or in the FILE menu, click Rename. This highlights the binder name at the top of the page and allows you to type in a new name. After typing in the new name, hit Enter to commit.
Or in your Table of Contents drawer, click Binder Information.
In the dialog box, type in a new binder name and click SAVE INFORMATION. You can also get to that same dialog box from your Alerts page by clicking on the binder name.
