After getting used to the Space Cadet style of typing, you may wish to enable
this sort of functionality on other keys, as well. Fortunately, the Space Cadet
plugin is configurable and extensible to support adding symbols to other keys.
Along with `(` on your left `Shift` key and `)` on your right `Shift` key,
you may wish to add other such programming mainstays as `{` to your left-side `cmd` key,
`}` to your right-side `alt` key, `[` to your left `Control` key, and `]` to your right
`Control` key. You can map the keys in whatever way you may wish to do, so feel free to
experiment with different combinations and discover what works best for you!

If you wish to enable additional modifier keys (or disable the default behavior

passing a new keymap into the SpaceCadet object, as shown below:
