You're right that having multiple curly brackets everywhere is a bid
tedious. One of the Palettes (Basic Input) has a 2x2 matrix on it, but
that's pretty limiting.

My way of doing it, which works for square matrices is to execute e.g.

IdentityMatrix[6]//MatrixForm

Copy the output and paste it into a new input line, and - hey presto - you
have a 6x6 matrix where you can edit the entries - put any other definitions
around it and it works fine.

I'm sure that you can also do this for non-square matrices, and create your
own palettes, but I've never bothered myself!
