Regarding the double brackets for representing Part, you can instead use〚 and 〛which can be input with `ESC`-[-[-`ESC` and `ESC`-]-]-`ESC` respectively. This makes the code prettier and easier to read. There is a very easy to implement modification you can make to allow the keyboard shortcuts `CMD`-[ and `CMD`-] for the double bracket symbol, which is described here: http://szhorvat.net/pelican/pages/mathematica.html http://szhorvat.net/pelican/pages/mathematica.html I rather wish Wolfram would provide these keyboard shortcuts in the base software
