Much thanks Cairn4, switching to another keyboard worked. A toggle would be great as my other keyboard is way too mushy. Just a suggestion: is there maybe a way to have it do it's detection in the settings menu and have the user confirm the device is a controller? That way you don't have to program in exceptions for every device that might do this and save some time for more awesome content :)
As for the control mapping issue in the menu, it appears to be both main menu and in-game menus. I was playing around with it a bit and noticed it is working right for all the other settings, but the 'tech upgrades' hotkey displays whatever setting the 'map' hotkey is set to. However: it seems to be actually mapping 'tech upgrades' to the key I try to set it to and just displaying it in the menu wrong. I bet this is just it referencing the wrong variable when the menu is pulled up.
