Multiple keys combination for same command

[vtmx]

Is possible create a shortcut with Key A or Key B to execute the same command?

# not working
super + {_,shift + }{h|Left,j|Down,k|Up,l|Right}
	bspc node -{f,s} {west,south,north,east}

Today I do:

# working
super + {_,shift + }{h,Left,j,Down,k,Up,l,Right}
	bspc node -{f,s} {west,west,south,south,north,north,east,east}
