+# Quantum Keycodes
+
+Something important to realise with keycodes is that they are all numbers between `0x0` and `0xFFFF` - even though they may look like functions, words, or phrases, they are all shortcuts to some number. This allows us to define all of what they do in different places, and store keymaps in a relatively small place (arrays). If you try to "call" a keycode by placing it somewhere besides a keymap, it may compile, but it won't do anything useful.
+
+All keycodes on this page have a value above `0xFF` (values less are considered the [basic keycodes](basic_keycodes.md)) and won't work with any of the mod/layer-tap keys listed at the bottom.
+
+* `SAFE_RANGE` is always the last keycode in the quantum list, and where custom lists can begin
+* `RESET` puts the keyboard into DFU mode for flashing
+* `DEBUG` toggles debug mode
+* Shortcuts for bootmagic options (work when bootmagic is off)
+ * `MAGIC_SWAP_CONTROL_CAPSLOCK`
+ * `MAGIC_CAPSLOCK_TO_CONTROL`
+ * `MAGIC_SWAP_LALT_LGUI`
+ * `MAGIC_SWAP_RALT_RGUI`
+ * `MAGIC_NO_GUI`
+ * `MAGIC_SWAP_GRAVE_ESC`
+ * `MAGIC_SWAP_BACKSLASH_BACKSPACE`

+ * `MAGIC_UNSWAP_GRAVE_ESC`
+ * `MAGIC_UNSWAP_BACKSLASH_BACKSPACE`
+ * `MAGIC_UNHOST_NKRO`
+ * `MAGIC_UNSWAP_ALT_GUI`/`AG_NORM`
+ * `MAGIC_TOGGLE_NKRO`
+* `KC_GESC`/`GRAVE_ESC` acts as escape when pressed normally but when pressed with a mod will send a `~`
+* `KC_LSPO` left shift when held, open paranthesis when tapped
+* `KC_RSPC` right shift when held, close paranthesis when tapped
+* `KC_LEAD` the leader key
+
+* `FUNC(n)`/`F(n)` to call `fn_action` n
+* `M(n)` to call macro n
+* `MACROTAP(n)` to macro-tap n idk FIXME

+
+### Mod-tap keys
+
+These keycodes will press the mod(s) when held, and the key when tapped. They only work with [basic keycodes](basic_keycodes.md).

+## Shifted symbols
+
+It's important to remember that all of the keycodes also send a left shift - this may cause unintended actions if unaccounted for. The 4-letter code is preferred in most situations.
+
+* `KC_TILD`/`KC_TILDE` tilde `~`
+* `KC_EXLM`/`KC_EXCLAIM` exclamation mark `!`
+* `KC_AT` at sign `@`
+* `KC_HASH` hash sign `#`
+* `KC_DLR`/`KC_DOLLAR` dollar sign `$`
+* `KC_PERC`/`KC_PERCENT` percent sign `%`
+* `KC_CIRC`/`KC_CIRCUMFLEX` circumflex `^`

+
+## Layer adjustments
+
+* `LT(layer, kc)` turn on layer (0-15) when held, kc ([basic keycodes](basic_keycodes.md)) when tapped
+* `TO(layer)` turn on layer when depressed
+* `MO(layer)` momentarily turn on layer when depressed (requires `KC_TRNS` on destination layer)
+* `DF(layer)` sets the base (default) layer
+* `TG(layer)` toggle layer on/off
+* `OSL(layer)` switch to layer for one keycode
+* `TT(layer)` tap toggle? idk FIXME
+
+## Unicode
+
+* `UNICODE(n)`/`UC(n)` if `UNICODE_ENABLE`, this will send characters up to `0x7FFF`
+* `X(n)` if `UNICODEMAP_ENABLE`, also sends unicode via a different method \ No newline at end of file
