Huntsman Elite, issues with Ctrl + Shift + F

I bought the keyboard in hopes of using it for my personal programming.



When in an IDE (Visual Studio 2017 or Jetbrains Rider), I cannot seem to press Ctrl + Shift + F.



I found an online keyboard debugger (https://codepen.io/QDeltaE/pen/PjXWZr)

and I've been playing around with it. Here are my logs in testing:



Ctrl + F:

>Keydown ↓ Key: "Control" KeyCode: 17

>Keydown ↓ Key: "f" KeyCode: 70

>Keyup ↑ Key: "f" KeyCode: 70

>Keyup ↑ Key: "Control" KeyCode: 17



Shift + F:

>Keydown ↓ Key: "Shift" KeyCode: 16

>Keydown ↓ Key: "F" KeyCode: 70

>Keyup ↑ Key: "F" KeyCode: 70

>Keyup ↑ Key: "Shift" KeyCode: 16



Ctrl + Shift + F

>Keydown ↓ Key: "Control" KeyCode: 17

>Keydown ↓ Key: "Shift" KeyCode: 16

>Keyup ↑ Key: "F" KeyCode: 70

>Keyup ↑ Key: "Shift" KeyCode: 16

>Keyup ↑ Key: "Control" KeyCode: 17



If you look closely, you'll notice that the F key never gets a key-down event when both Ctrl and Shift are pressed.



Being able to use Find In Path / Find in Files for a programmer is crucial.



D, for instance, doesn't have the issue:

>Keydown ↓ Key: "Control" KeyCode: 17

>Keydown ↓ Key: "Shift" KeyCode: 16

>Keydown ↓ Key: "D" KeyCode: 68

>Keyup ↑ Key: "D" KeyCode: 68

>Keyup ↑ Key: "Shift" KeyCode: 16

>Keyup ↑ Key: "Control" KeyCode: 17



So it doesn't seem to be an issue with the modifiers blocking keys, but I'm thinking that something is intercepting this set of keys. Anyone know how to track down what it is and disable it?
