 Selectors are a very useful idea and can do more that apply styles. We can also find widgets in Python code with selectors, and make updates to widgets in a simple expressive way. Let's look at how!

 Let's say we have a query which gets all the buttons in an app, and we want a new query object with just the disabled buttons. We could write something like this:
 
 ```python
 # Get all the Buttons
-buttons_query = self.query("Button") 
+buttons_query = self.query("Button")
 # Buttons with 'disabled' CSS class
-disabled_buttons = buttons_query.filter(".disabled") 
+disabled_buttons = buttons_query.filter(".disabled")
 ```
 
 Iterating over `disabled_buttons` will give us all the disabled buttons.
 
 ## Exclude
 
-Query objects have a [exclude][textual.css.query.DOMQuery.exclude] method which is the logical opposite of [filter][textual.css.query.DOMQuery.filter]. The `exclude` method removes any widgets from the query object which match a selector.

 Here's how we could get all the buttons which *don't* have the `disabled` class set.
