Double-shift as Leader Key

I found it most convenient to use left shift + right shift together as a leader key. It's easy to memorize, hard to do accidentally and easy to do purposefully.

To do this with Karabiner Elements, do the following:

1. In the Karabiner Elements settings UI, go to Complex Modifications

2. Click Add Your Own Rule

3. Paste in the following JSON:

   {
       "description": "Left_Shift + Right_Shift -> F13",
       "manipulators": [
           {
               "from": {
                   "key_code": "left_shift",
                   "modifiers": {
                       "mandatory": ["right_shift"],
                       "optional": ["caps_lock"]
                   }
               },
               "to": [
                   {
                       "key_code": "f13",
                       "modifiers": []
                   }
               ],
               "type": "basic"
           },
           {
               "from": {
                   "key_code": "right_shift",
                   "modifiers": {
                       "mandatory": ["left_shift"],
                       "optional": ["caps_lock"]
                   }
               },
               "to": [
                   {
                       "key_code": "f13",
                       "modifiers": []
                   }
               ],
               "type": "basic"
           }
       ]
   }

   This will trigger an F13 Key press when both shift keys are pressed together.

4. In LeaderKey settings, bind F13 as your leader key:

Nothing crazy, I tend to keep my workflow rather simple. The "tree" is organized such that:

1. Very frequently accessed programs (browser, terminal, webcam controller) are top level, one key press away
2. Other common programs live under p for "programs"
3. System settings live under s for "settings"
4. Window management lives under w for "window"
