Description
a = KeyedArray(rand(2, 3), down=[1, 2], across=[1.0, 2.0, 3.0])
b = KeyedArray(rand(1, 3), down=[1], across=[1.0, 2.0, 3.0])
julia> a[down=1] += b[down=1]
ERROR: MethodError: no method matching setindex!(::KeyedArray{Float64, 2, NamedDimsArray{(:down, :across), Float64, 2, Matrix{Float64}}, Tuple{Vector{Int64}, Vector{Float64}}}, ::KeyedArray{Float64, 1, NamedDimsArray{(:across,), Float64, 1, Vector{Float64}}, Base.RefValue{Vector{Float64}}}; down=1)
Closest candidates are:
setindex!(::KeyedArray, ::Any, ::Any...) at /Users/mzgubic/.julia/packages/AxisKeys/G3Okw/src/struct.jl:129 got unsupported keyword argument "down"
setindex!(::AbstractArray, ::Any, ::Any...) at abstractarray.jl:1264 got unsupported keyword argument "down"

Research direction
Reproduce the example with KeyedArray and inspect setindex! in src/struct.jl around line 129. Determine the intended behavior for a[down=1] += b[down=1]; done should be established by a regression test showing whether this keyword-indexed assignment is supported.
