How do I get the key of a keybind in Forge? (1.8.9)

[Blackvault]

Hi

I need help to get the key from a keybind for my mod. I'm trying to use

Minecraft.getMinecraft().gamesettings.keyBindAttack().toString():

but it didn't work. It didn't return the key of the keybind. How do I get it?

btw I accidentally typed colon in the code thing but I meant semicolon
