My organization has a lot of instances where someone needs to communicate a listview to another individual. Unfortunately, Salesforce does not refresh the listview's ID (my.salesforce.com/[This is the ID]) when a listview is selected. 

To facilitate communications, I'd like to place a custom button that pre-populates an email form with this ID in the send field. Many of us have seen how to "hack" the URL applications in Salesforce, and I was wondering if I could get something like {!$Currentpage.URL} to work for that field.

Is there any way to capture the current listview and place it in an email field?

 I've got a button that executes javascript like this: 

location.replace('/email/author/emailauthor.jsp?retURL=/{!Case.Id}&p3_lkid={!Case.Id}&rtype=003&p7=[ThisIsTheCurrentURL]&p2_lkid={!Case.ContactId}&template_id=00Xc0000000HrOk');

p7 refers to the field in which I'd like to insert the previous page's URL into, or at least listview ID into.

Here's a selection of the source code for the listview selection, I'm wondering if I can capture the selected value from here at least.
