What is the function for 'fn' button in my Macbook Pro ?

so...........?

for all the keys

If you look at your keyboard, there are alternative symbols other than the ones you type, e.g. numbers on "u, i, o, j, k, l, m" and the function keys. If you hold the fn key when pressing the letters, they alwasy print the numbers.

If you hold it and press a function key (F1-F12) it switches the functionality from the mapped F keys to the laptop-specific function (screen brightness, etc.). You can reverse that in the keyboard pref.

Have you tried googling?
If you have software features being controlled by the f1-f10 keys, then holding 'fn'+one of those keys will perform the action pictured on the key.

There are also other functions, like fn+delete that performs a backwards delete.....

Most if not all laptops have the "fn" key.

Combining the fn key with other keys would give you special functions, as you would expect it to...

The function of the function button is to give you access to other functions. That is it's function. I learned that at a function I attended.

If you spent that much money on a MacBook Pro and you don't know what the "fn" keys are for, you would be best served by reviewing the Owner's Manual to understand the capabilities of the MacBook Pro.

Out of curiosity, what do you plan to use the MacBook Pro for?
