Matti-Oskari Leppänen <mongrel@mindless.com> suggested the following:

I think that you should mention somewhere in documents how to make
shift-arrow etc. work under linux-console ... because it's quite simple

just make file that has following lines save it as some.map and
loadkeys some.map then you have same keysyms as used in wmark.sl
