what are some unused for free keybinds?

[Catamer]

I'm using Innersapce + Jamba, I was wondering what are a few free or unused keybinding that I can use?
now that I have an x-keys desktop I want to add a few special casts that are beyond 0 through =, like eating food.

You can use basically whatever keys you want.
I've got a G15, so have moved several of the default binds to the G15 keys.

I'm using:
M1 = Keyboard Repeater On/Off
M2 = Mouse Repeater On/Off
M3 = Keymaps On/Off
MR = Follow
Mouse 4 = Follow
G01 = Interact With Target
G06 = Toggle Melee IWT (built into my DPS 1-3 keys) On/Off.
G13 = Switch to Slot 1
G14 = Switch to Slot 2
G15 = Switch to Slot 3
G16 = Switch to Slot 4
G17 = Switch to Slot 5
G18 = Invite Group

I use:
1 through =.
Shift A through Shift ;
Shift F1 through Shift F12
F (FTL Assist Me)
Backslash (FTL Target Me)

A few other assorted keys:
- Backspace, Shift Tilde, T (warlock teams).

Arrow Keys:
- Independent Slave Movement.

I have Repeater Regions over some buttons:
- Hearthstones, Healthstones, Dailies Macro Button
