Scrolling the map in windowed mode

[Captain_Cruft]

I find "auto-scrolling" in windowed mode rather difficult. The reason being that once the mouse pointer goes out of the SPMBT window movement stops. You have to actually hover the mouse near the edge of the window, which is not the way my arm has learnt to do it

So, I was wondering if there was any coding solution to this? Alternatively, keyboard scrolling might be an option but not using the default cursor keys. I like to drive two-handed and they are in a bad position for my left hand ... Any chance of allowing these keys to be re-mapped?
