@raghukamath Oh yes, this Debian policy to not get the bpf system in their default kernels is really a pain...
I haven't retried the input-remapper in age with this device and forgot about it: can it bypass the two key shortcut and assign instead only a single keypress? (eg. reassigning the Ctrl+O to a simple B?)
@davidrevoy Yes it can, I have mapped it to E key. The only issue I found that it is hard to map Ctrl N since input remapper captures this as a shortcut for itself to create a new shortcut entry scheme :) so it drops your exisiting changes when you press Ctrl N and creates new list of entries :P. May be worth filing a bug with input remapper but I did not have time to check it out further.
