So I am on a windows keyboard where there is a shortcut. Fn+Space allows you to change the lights on the keys. However, when I press Fn+Space, my Minecraft character keeps jumping without me pressing space.
How to replicate:
1: Get a windows computer that has the shortcut I specified.
2: Hold Fn and then press space.
3: Let go of the keyboard.
4: Your character should continuously jump
