netbeans background color

(I want this just so I can browse my files easi开发者_如何学运维ly instead of just walls of text)

I am using Netbeans 7 and I want to know: can I mark functions/classes or blocks with a background color?

Example: I want to make the background of a function called getDate() green, then I can see only that block with a green background:

// this block appears with a green background
function getDate() {
}


// this block appears with a red background
function setDate() {
}

I think you can change the background-color of all functions, but not for one in particular

How would you manage that anyway? By function name or signature?
