11.1 Customize Hotkeys
From 3D-Coat Wiki
To define a hotkey is actually quite simple. All you need to do is point your mouse cursor over the item you would like to set a hotkey for and then press the END key, you will then see the following prompt. You can now press the key you would like to assign to the function. Keep in mind nearly every button or menu item you see in 3D-Coat be have a custom hotkey. Also, if a hotkey is already taken, it is no problem to go ahead an re-assign the key to whatever you like.
