Use arrow keys to scroll through policies

Might sound minor, but in the unimplemented policies section it’s a little annoying to compare effects. If I wish to look through a bunch of policies sequentially I need to look left, click on the policy, look right to see its effects, then look left again to click the next policy, etc. It would be easier if we could just use the up/down arrow keys. You could utilise the left/right arrow keys to change between the category column and the policies column (i.e. the column with “foreign policy”, “welfare”, etc. and the column with the individual policies).

Maybe you could also implement some kind of comparison option where you can select two policies and do a side by side comparison?
