Adopt more Mac keyboard shortcuts standards found in other IDEs

Using Xcode and Sublime 2, TextWrangler (and more) as examples...
Pycharm on the Mac doesn't follow what a lot of Mac developers has been use wrt/keyboard short cuts.
It would help adoption and not learn another set of shortcuts

Here is a good example:
Un-indedent: Apple [
Pycharm Un-indent: different

Block Indent:  Apple ]
Pycharm Indent: different

Many more examples.

Just a suggestion...
