Collapse All in TextMate

Is t开发者_开发知识库here a way to collapse all the functions in a given php file in TextMate?

For example I have two methods:

function index() {
    //Sample code   
}

function beforeFilter() {
    //Sample Code
}

I would like to be able to issue a command where all the methods will collapse to:

function index() { ...

function beforeFilter() { ...

Thanks!

Via the menu:

View > Toggle foldings at Level > All levels

or shortcut:

ALT + ⌘ + 0
