On a side note: The GitHub issues functionality is the best way to report issues with the BigBag files. However, I'll happily answer here too, it's just a bit more messy and harder to find afterwards.
Try updating to the latest commit. I had a wrong scan code for the <BKSP> key in the extend file (it was incorrectly called <BACK>, an artefact of me working cross-platform).
Here's the current Backspace mapping:
key <BKSP> { symbols[Group1]=[Any , Any , Any , Any , // BackSpace
Pause , Pause , // Pause/Break
Pause , Pause ] , // (<BRK> is special)
actions[Group1]=[NoAction(), NoAction(), NoAction(), NoAction(),
Redirect(key=<PAUS>,clearmods=LevelFive), Redirect(key=<PAUS>,clearmods=LevelFive) ,
NoAction() , NoAction() ] ,
repeat=yes }; // BackSpace
If instead you want to output Ctrl+Backspace, it's doable I think. You'd want to use this I suppose:
key <BKSP> { symbols[Group1]=[Any , Any , Any , Any , // BackSpace
BackSpace , BackSpace , // Ctrl+Backspace (by action)
BackSpace , BackSpace ] , //
actions[Group1]=[NoAction(), NoAction(), NoAction(), NoAction(),
Redirect(key=<BKSP>,mods=Control,clearmods=LevelFive), Redirect(key=<BKSP>,mods=Shift+Control,clearmods=LevelFive), // Ctrl+Back
Redirect(key=<BKSP>,mods=Control,clearmods=LevelFive), Redirect(key=<BKSP>,mods=Shift+Control,clearmods=LevelFive)], // Ctrl+Back
repeat=yes }; // BackSpace
Please let me know if that works!
