+# Charybdis (3x5) default keymap
+
+> :bulb: Have a look at the [`via` keymap](../via) for a more feature-rich layout.
+
+The Charydbis (3x5) default keymap is inspired from the original [Dactyl Manuform](../../../../../handwired/dactyl_manuform) default keymap.
+
+This layout supports RGB matrix. However, due to space constraints on the MCU, only a limited number of effect can be enabled at once. Look at the `config.h` file and enable your favorite effect.

+# Charybdis (3x5) `via` keymap
+
+The Charydbis (3x5) `via` keymap is based on a QWERTY layout with [home row mods](https://precondition.github.io/home-row-mods) and [Miryoku-inspired layers](https://github.com/manna-harbour/miryoku), and some features and changes specific to the Charybdis.
+
+This layout supports RGB matrix. However, due to space constraints on the MCU, only a limited number of effect can be enabled at once. Look at the `config.h` file and enable your favorite effect.
+
+This layout also supports VIA.
+
+## Customizing the keymap
+
+### Dynamic DPI scaling
+
+Use the following keycodes to change the default DPI:
+
+- `POINTER_DEFAULT_DPI_FORWARD`: increases the DPI; decreases when shifted;
+- `POINTER_DEFAULT_DPI_REVERSE`: decreases the DPI; increases when shifted.
+
+There's a maximum of 16 possible values for the sniping mode DPI. See the [Charybdis documentation](../../README.md) for more information.
+
+Use the following keycodes to change the sniping mode DPI:
+
+- `POINTER_SNIPING_DPI_FORWARD`: increases the DPI; decreases when shifted;
+- `POINTER_SNIPING_DPI_REVERSE`: decreases the DPI; increases when shifted.
+
+There's a maximum of 4 possible values for the sniping mode DPI. See the [Charybdis documentation](../../README.md) for more information.
+
+### Drag-scroll
+
+Use the `DRAGSCROLL_MODE` keycode to enable drag-scroll on hold. Use the `DRAGSCROLL_TOGGLE` keycode to enable/disable drag-scroll on key press.
+
+### Sniping
+
+Use the `SNIPING_MODE` keycode to enable sniping mode on hold. Use the `SNIPING_TOGGLE` keycode to enable/disable sniping mode on key press.
+
+Change the value of `CHARYBDIS_AUTO_SNIPING_ON_LAYER` to automatically enable sniping mode on layer change. By default, sniping mode is enabled on the pointer layer:
+
+```c
+#define CHARYBDIS_AUTO_SNIPING_ON_LAYER LAYER_POINTER
+```
+
+### Auto pointer layer
+
+The pointer layer can be automatically enabled when moving the trackball. To enable or disable this behavior, add or remove the following define:
+
+```c
+#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_ENABLE
+```
+
+By default, the layer is turned off 1 second after the last registered trackball movement:
+
+```c
+#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_TIMEOUT_MS 1000
+```
+
+The trigger sensibility can also be tuned. The lower the value, the more sensible the trigger:
+
+```c
+#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_THRESHOLD 8
+```
+

+# Charybdis (4x6) default keymap
+
+> :bulb: Have a look at the [`via` keymap](../via) for a more feature-rich layout.
+
+The Charydbis (4x6) default keymap is inspired from the original [Dactyl Manuform](../../../../../handwired/dactyl_manuform) default keymap.
+
+This layout supports RGB matrix. However, due to space constraints on the MCU, only a limited number of effect can be enabled at once. Look at the `config.h` file and enable your favorite effect.

+# Charybdis (4x6) `via` keymap
+
+The Charydbis (4x6) `via` keymap is inspired from the original [Dactyl Manuform](../../../../../handwired/dactyl_manuform) default keymap, with some features and changes specific to the Charybdis.
+
+This layout supports RGB matrix. However, due to space constraints on the MCU, only a limited number of effect can be enabled at once. Look at the `config.h` file and enable your favorite effect.
+
+## Customizing the keymap
+
+### Dynamic DPI scaling
+
+Use the following keycodes to change the default DPI:
+
+- `POINTER_DEFAULT_DPI_FORWARD`: increases the DPI; decreases when shifted;
+- `POINTER_DEFAULT_DPI_REVERSE`: decreases the DPI; increases when shifted.
+
+There's a maximum of 16 possible values for the sniping mode DPI. See the [Charybdis documentation](../../README.md) for more information.
+
+Use the following keycodes to change the sniping mode DPI:
+
+- `POINTER_SNIPING_DPI_FORWARD`: increases the DPI; decreases when shifted;
+- `POINTER_SNIPING_DPI_REVERSE`: decreases the DPI; increases when shifted.
+
+There's a maximum of 4 possible values for the sniping mode DPI. See the [Charybdis documentation](../../README.md) for more information.
+
+### Drag-scroll
+
+Use the `DRAGSCROLL_MODE` keycode to enable drag-scroll on hold. Use the `DRAGSCROLL_TOGGLE` keycode to enable/disable drag-scroll on key press.
+
+### Sniping
+
+Use the `SNIPING_MODE` keycode to enable sniping mode on hold. Use the `SNIPING_TOGGLE` keycode to enable/disable sniping mode on key press.
+
+Change the value of `CHARYBDIS_AUTO_SNIPING_ON_LAYER` to automatically enable sniping mode on layer change. By default, sniping mode is enabled on the pointer layer:
+
+```c
+#define CHARYBDIS_AUTO_SNIPING_ON_LAYER LAYER_POINTER
+```
+
+### Auto pointer layer
+
+The pointer layer can be automatically enabled when moving the trackball. To enable or disable this behavior, add or remove the following define:
+
+```c
+#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_ENABLE
+```
+
+By default, the layer is turned off 1 second after the last registered trackball movement:
+
+```c
+#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_TIMEOUT_MS 1000
+```
+
+The trigger sensibility can also be tuned. The lower the value, the more sensible the trigger:
+
+```c
+#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_THRESHOLD 8
+```

+# Charybdis (4x6)
+
+An ergonomic keyboard with integrated trackball.
+
+The Charybdis is available in 4x6 and 3x5 form factor at [bastardkb.com](https://bastardkb.com).
+
+## Keymaps
+
+### [`default`](keymaps/default)
+
+A simple QWERTY layout with 3 layers.
+
+### [`via`](keymaps/via)
+
+Same as the [default](keymaps/default) keymap, but with VIA support.

+Check out the [keyboard build guides](https://docs.bastardkb.com) for the Charybdis and other ergonomic keyboards.
+
+## Building the firmware
+
+### Charybdis (4x6)
+
+The `default` keymap is inspired from the original [Dactyl Manuform](../../handwired/dactyl_manuform) layout.
+
+```shell
+qmk compile -kb bastardkb/charybdis/4x6 -km default
+```
+
+Check out the `via` layout if you're looking for VIA support:
+
+```shell
+qmk compile -kb bastardkb/charybdis/4x6 -km via
+```
+
+### Charybdis (3x5)
+
+The `default` keymap is inspired from the original [Dactyl Manuform](../../handwired/dactyl_manuform) layout.
+
+```shell
+qmk compile -kb bastardkb/charybdis/3x5 -km default
+```
+
+Check out the `via` layout if you're looking for VIA support:
+
+```shell
+qmk compile -kb bastardkb/charybdis/3x5 -km via
+```
+
+## Customizing the firmware
+
+### Dynamic DPI scaling
+
+The pointer's DPI can be changed at runtime.
+
+By default, the DPI is set to `400`. The Charybdis supports up to 16 different DPI values. By default, it cycles between `400` and `3400`, with a step of `200` (_ie._ `400`, `600`, `800`, …, `3400`).
+
+Calling `charybdis_cycle_pointer_default_dpi(bool forward)` will cycle forward or backward the possible values.
+
+Use `charybdis_cycle_pointer_default_dpi_noeeprom(bool forward)` to change the DPI value without persisting the change to EEPROM (_ie._ resetting the board will revert to the last saved value).
+
+`charybdis_get_pointer_default_dpi()` returns the current DPI value.
+
+This behavior can be further customized with the following defines:
+
+```c
+#define CHARYBDIS_MINIMUM_DEFAULT_DPI 400
+#define CHARYBDIS_DEFAULT_DPI_CONFIG_STEP 200
+```
+
+### Drag-scroll
+
+Drag-scroll enables scrolling with the trackball. When drag-scroll is enabled, the trackball's `x` and `y` movements are converted into `h` (horizontal) and `v` (vertical) movement, effectively sending scroll instructions to the host system.
+
+Call `charybdis_set_pointer_dragscroll_enabled(bool enable)` to enable/disable drag-scroll.
+
+`charybdis_get_pointer_dragscroll_enabled()` returns whether sniping mode is currently enabled.
+
+To invert the horizontal scrolling direction, define `CHARYBDIS_DRAGSCROLL_REVERSE_X`:
+
+```c
+#define CHARYBDIS_DRAGSCROLL_REVERSE_X
+```
+
+To invert the vertical scrolling direction (_ie._ mimic macOS "natural" scroll direction), define `CHARYBDIS_DRAGSCROLL_REVERSE_Y`:
+
+```c
+#define CHARYBDIS_DRAGSCROLL_REVERSE_Y
+```
+
+This only affects the vertical scroll direction.
+
+### Sniping mode
+
+Sniping mode slows down the pointer for more precise gestures. It is useful when combined with a higher default DPI.
+
+Call `charybdis_set_pointer_sniping_enabled(bool enable)` to enable/disable sniping mode.
+
+`charybdis_get_pointer_sniping_enabled()` returns whether sniping mode is currently enabled.
+
+Like the default pointer's DPI, the sniper mode DPI can be changed at runtime.
+
+By default, sniping mode lowers the DPI to `200`. This can be changed at runtime: the Charybdis supports up to 4 different DPI values for sniping mode. By default, it cycles between `200`, `300`, `400` and `500`.
+
+Calling `charybdis_cycle_pointer_sniping_dpi(bool forward)` will cycle forward or backward the possible values.
+
+Use `charybdis_cycle_pointer_sniping_dpi_noeeprom(bool forward)` to change the sniping mode DPI value without persisting the change to EEPROM (_ie._ resetting the board will revert to the last saved value).
+
+`charybdis_get_pointer_sniping_dpi()` returns the current sniping mode DPI value.
+
+This behavior can be further customized with the following defines:
+
+```c
+#define CHARYBDIS_MINIMUM_SNIPING_DPI 200
+#define CHARYBDIS_SNIPING_DPI_CONFIG_STEP 100
+```
+
+### Acceleration
+
+By default, the pointer's movements are linear. To enable acceleration, add the following define:
+
+```c
+#define CHARYBDIS_POINTER_ACCELERATION_ENABLE
+```
+
+The acceleration factor can be further tune _via_ the `CHARYBDIS_POINTER_ACCELERATION_FACTOR`:
+
+```c
+#define CHARYBDIS_POINTER_ACCELERATION_FACTOR 24
+```
+
+### Custom keycodes
+
+The Charybdis firmware defines a number of keycodes to leverage its features, namely:
+
+```
+#ifndef NO_CHARYBDIS_KEYCODES
+enum charybdis_keycodes {
+ POINTER_DEFAULT_DPI_FORWARD = SAFE_RANGE,
+ POINTER_DEFAULT_DPI_REVERSE,
+ POINTER_SNIPING_DPI_FORWARD,
+ POINTER_SNIPING_DPI_REVERSE,
+ SNIPING_MODE,
+ SNIPING_MODE_TOGGLE,
+ DRAGSCROLL_MODE,
+ DRAGSCROLL_MODE_TOGGLE,
+ CHARYBDIS_SAFE_RANGE,
+};
+
+#define DPI_MOD POINTER_DEFAULT_DPI_FORWARD
+#define DPI_RMOD POINTER_DEFAULT_DPI_REVERSE
+#define S_D_MOD POINTER_SNIPING_DPI_FORWARD
+#define S_D_RMOD POINTER_SNIPING_DPI_REVERSE
+#define SNIPING SNIPING_MODE
+#define SNP_TOG SNIPING_MODE_TOGGLE
+#define DRGSCRL DRAGSCROLL_MODE
+#define DRG_TOG DRAGSCROLL_MODE_TOGGLE
+#endif // !NO_CHARYBDIS_KEYCODES
+```
+
+Users extending the keycode set themselves (either in their keymap, or in their userspace) must start at `CHARYBDIS_SAFE_RANGE` to avoid conflicts, _eg._:
+
+```c
+enum userspace_keycodes {
+#ifndef NO_CHARYBDIS_KEYCODES
+ MY_FIRST_KEYCODE = CHARYBDIS_SAFE_RANGE,
+#else
+ MY_FIRST_KEYCODE = SAFE_RANGE,
+#endif // !NO_CHARYBDIS_KEYCODES
+ MY_SECOND_KEYCODE,
+ …
+};
+```
+
+To disable the custom keycodes, and reduce binary size, simply add a definition in `config.h`:
+
+```c
+#define NO_CHARYBDIS_KEYCODES
+```
