Snippets: How to delete placeholders on tab

[DrZYin]

For example, in this snippet:

function functionName(parameter) {
  // ...
}

functionName, parameter and //… are placeholders. If I simply tab through them, they won’t be deleted. But there’re often cases when I need anonymous functions with no arguments, so I always have to press backspace before tabbing. Is there a way to delete placeholders on tab?

Thanks!
