Can not change .lua file on my keybow

hi, my default.lue file which i need to change to map out keys on my keybow is not able to be edited.How can i make it so that i can change the keys? thanks

How are you attempting to edit it, and what happens when you try to edit it?

hi alphanumeric, i am trying to edit it with a program named VIM , but it saves it as a .lua` and i have to revert it back to normal. Then i try and boot up my keybow and nothing happens, leds are on but no feedback, all i did in default.lua was change it from the numbers 0-10 and . to f1-f12. many thanks

I usually just use nano as my editor. Anyway have you seen this?
