### Space Cadet Shift: The future, built in
Steve Losh [described](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/) the Space Cadet Shift quite well. Essentially, you hit the left Shift on its own, and you get an opening parenthesis; hit the right Shift on its own, and you get the closing one. When hit with other keys, the Shift key keeps working as it always does. Yes, it's as cool as it sounds.
To use it, use `KC_LSPO` (Left Shift, Parens Open) for your left Shift on your keymap, and `KC_RSPC` (Right Shift, Parens Close) for your right Shift.
The only other thing you're going to want to do is create a `makefile.mk` in your keymap directory and set the following:
```
COMMAND_ENABLE = no # Commands for debug and configuration
```
This is just to keep the keyboard from going into command mode when you hold both Shift keys at the same time.
### The Leader key: A new kind of modifier
If you've ever used Vim, you know what a Leader key is. If not, you're about to discover a wonderful concept. :) Instead of hitting Alt+Shift+W for example (holding down three keys at the same time), what if you could hit a _sequence_ of keys instead? So you'd hit our special modifier (the Leader key), followed by W and then C (just a rapid succession of keys), and something would happen.

It's best to declare the `static uint16_t key_timer;` outside of the macro block (top of file, etc).
#### Example 1: Single-key copy/paste (hold to copy, tap to paste)
#### Example: Single-key copy/paste (hold to copy, tap to paste)
With QMK, it's easy to make one key do two things, as long as one of those things is being a modifier. :) So if you want a key to act as Ctrl when held and send the letter R when tapped, that's easy: `CTL_T(KC_R)`. But what do you do when you want that key to send Ctrl-V (paste) when tapped, and Ctrl-C (copy) when held?
And then, to assign this macro to a key on your keyboard layout, you just use `M(0)` on the key you want to press for copy/paste.
#### Example 2: Space Cadet Shift (making it easy to send opening and closing parentheses)
In the [Modern Space Cadet Keyboard](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/#shift-parentheses), one of cooler features is the Shift Parentheses. To quote Steve Losh:
> When held while pressing other keys, act like Shift.
> When pressed and released on their own, type an opening or closing parenthesis (left and right shift respectively).
key_timer = timer_read(); // if the key is being pressed, we start the timer.
register_code(KC_LSFT); // we're now holding down Shift.
} else { // this means the key was just released, so we can figure out how long it was pressed for (tap or "held down").
if (timer_elapsed(key_timer) <150){//150being150ms,thethreshholdwepickforcountingsomethingasatap.
register_code(KC_9); // sending 9 while Shift is held down gives us an opening paren
unregister_code(KC_9); // now let's let go of that key
}
unregister_code(KC_LSFT); // let's release the Shift key now.
}
break;
}
case 1: {
if (record->event.pressed) {
key_timer = timer_read(); // Now we're doing the same thing, only for the right shift/close paren key
register_code(KC_RSFT);
} else {
if (timer_elapsed(key_timer) <150){
register_code(KC_0);
unregister_code(KC_0);
}
unregister_code(KC_RSFT);
}
break;
}
}
return MACRO_NONE;
};
```
And then, to assign this macro to a key on your keyboard layout, you just use `M(0)` on the key you want to press for left shift/opening parens, and `M(1)` for right shift/closing parens.
## Additional keycode aliases for software-implemented layouts (Colemak, Dvorak, etc)
Everything is assuming you're in Qwerty (in software) by default, but there is built-in support for using a Colemak or Dvorak layout by including this at the top of your keymap:
