Screen1 Region1 (big one) has Region1.kcl set in maxmizer
TopLeft on Screen 2 has Region2.kcl set in maximizer
TopRight on Screen 2 has Region3.kcl set in maxmizer
BottomLeft on Screen 2 has Region4.kcl set in maximizer
BottomRight on Screen 2 has Region5.kcl set in maximizer

In addition, each command I start with has my keymaps with a single bind (- on main = Spread = strafe and move on slaves), this is done with 5 different keymaps and works.

When running my set up the window then says

wowmain kmap(r1.^)
wowslave1 kmap(r2.^)
wowslave2 kmap(r3.^)
wowslave3 kmap(r4.^)
wowslave4 kmap(r5.^)

Hitting comma moves wowslave3, region4.kcl backwards - and nothing else

Hitting period moves all but wowslave3, region4.kcl forwards - wowslave3, region4.kcl does nothing
