javascript: Backbonejs variable parameters

Consider this URL:

http://ift.tt/1EhfKoT

note:

#t=b

In this example, the variable "t" stores the current tab on the page where "b" is for billing.

How can I achieve query like parameters in backbone as shown above?

I understand Backbone has routes that support parameters in urls, but this is limited to when the data is in a hierarchy, for example: item/:id

But what about application settings that would not work well in a directory like structure?

The only solution I can think of is a custom parser and break up the key/values myself.

Any ideas?
