How to: Bind F13 to F24 keys on the G-keys (Logitech Gaming Keyboards)

logitech-bind-f13-f24.lua

-- How to use this script:
-- 1. Install the Logitech Gaming Software: http://support.logitech.com/en_us/software/lgs
-- 2. Launch it, and right click on your profile (the gear icon) and then click on "Scripts".
-- 3. Add the following code into the Script window, save it, and close it. Enjoy.
-- Now G1 is bound to F13, G2 to G14, ... G12 to F24.

function OnEvent(event, arg)

  -- OutputLogMessage("event = %s, arg = %s\n", event, arg) 

  fKey = {
    [1]  = 0x64, -- F13
    [2]  = 0x65, -- F14
    [3]  = 0x66, -- F15
    [4]  = 0x67, -- F16
    [5]  = 0x68, -- F17
    [6]  = 0x69, -- F18
    [7]  = 0x6A, -- F19
    [8]  = 0x6B, -- F20
    [9]  = 0x6C, -- F21
    [10] = 0x6D, -- F22
    [11] = 0x6E, -- F23
    [12] = 0x76  -- F24
  }

  if (event == "G_PRESSED") then
    PressKey(fKey[arg])
  end

  if (event == "G_RELEASED") then
    ReleaseKey(fKey[arg])
  end

end

Thank you so much this is exactly what I was looking for!

This is fantastic! Does it go any higher than f24 or is that the limit? I'm trying to fill out my g13 with empty function keys

I am not sure, but I don't think there is more than 24 function keys.

Thank you, I wasn't sure either. I wish there was lol

While this was extremely helpful in the past with Logi Gaming Software since it lacked bindings like this without scripting, it is no longer needed with Logi G Hub. You can now bind F13 through F24 through the UI to any of the G keys.

Those of you who use Gaming Software should remove it. It has been abandoned in favor of G Hub. It's last update was 2018-10-08. Newer devices are unsupported and Logitech no longer offers customer assistance with this software. They instead direct you to G Hub.

What if I want to do this same thing to my G600 mouse. Those G keys are G9-G20

Has it improved any? Last time I used it, I lost all the profiles I'd set up after a reboot, so I immediately switched back to LGS, which still works fine with the occasional hiccup.

Has it improved any?

It has improved a lot since my comment. Logitech Gaming Software (LGS) profiles are stored at C:\Users\<name>\Appdata\Local\Logitech\Logitech Gaming Software\Profiles.

1. Make sure LGHUB isn't installed at this time. Only LGS.
2. Copy the Logitech folder from AppData to temporary location (Desktop for example).
3. Uninstall LGS and reboot.
4. Copy the Logitech folder back to AppData.
5. Install LGHUB.
6. From the LGHUB interface, click the cog/gear icon top right.
7. Click "Import Profiles"
8. LGHUB will find and import + convert LGS profiles to be usable with LGHUB.

Note: Some devices are not supported in LGHUB and those device specific settings in profiles will not carry over.
