A backport of Keyboard Wizard for Minecraft forge 1.7.10 / 1.8.9.

Descriptions from the original mod:

The mod helps with solving key conflicts and finding unbound keys. It adds an "extra" controls GUI that displays an interactive keyboard in the center.

When you open the GUI(the hotkey is F8 by default) you will see a list of keybindings on the left, and a colored keyboard on the right.

White keys are unbound
Green keys have only one binding
Red keys have more than one binding

Click a key (or the mouse button) to set the binding selected in the list to that key.

Press the All Bindings button to select the category displayed in the binding list.

The binding list can be filtered by typing the bindings' names in the search bar below it. It can also be filtered by key name via surrounding the key's name in angle brackets, e.g. <Left Control>.

ATTENTION:

You DEFINITELY CAN add the mod to your modpack;
The mod needs Modern Keybinding as a dependency (and please notice that Modern Keybinding may need an extra dependency as well).
