Unable to modify BML settings in-game with only keyboard

[Xenapte]

All other settings in "Options" can be modified by using the keyboard, except those in the "Mods" page, i.e. BML settings. Once inside it the keyboard seems to lose function and only leaves you with the mouse to click everything.

(yeah it's true you can just use the mouse to get around - but sometimes it's very annoying since all other parts of the game can be controlled with keyboard only - and that's how most people do when they pause in-game to modify some settings)
