+# Aaron's KBD75v2 Mac-friendly ANSI 1u Layout
+
+This layout mimics the default KBD 75% ANSI 1u layout with a few mac-friendly tweaks. Because Mac OS uses a unique keycode
+for the Function key and only recognizes that keycode from keyboards registered with an Apple vendor ID ([see here for more info](https://beta.docs.qmk.fm/faqs/faq_keymap#fn-key-on-macos)),
+this layout uses custom macros and F-keycodes (F12, F13, etc) to provide Mac hotbar functionality (Print Screen, Launchpad, etc...) and maps the
+**Fn** key to the QMK momentary layer `_FN` (layer index 3) so it is listed as `MO(3)`.
+
+| Mac OS Keystroke | Description              | User-defined Macro | Layout Mapping   |
+| ---------------- | ------------------------ | ------------------ | ---------------- |
+| ⌘ + Shift + 3    | Print Screen             | `KC_CAPW`          | `Prt Scn`        |

+| F13              | Launchpad                |                    | `fn` + `Home`    |
+|                  | Colemak                  | `COLEMAK`          | `fn` + `C`       |
+|                  | Dvorak                   | `DVORAK`           | `fn` + `D`       |

+| `Ctrl` + `C`     | Quit/Break               | `KC_CTLC`          | `Pse Brk`        |
