Remove unnecessary IS_COMMAND definitions from recently added keyboards (#5065)

Did a big brane move and mixed those up. Been using this keyboard for weeks and never noticed.

 !> If you're having issues with OSM translating over Remote Desktop Connection, this can be fixed by opening the settings, going to the "Local Resources" tap, and in the keyboard section, change the drop down to "On this Computer".  This will fix the issue and allow OSM to function properly over Remote Desktop.
 
+## Callbacks
+
+When you'd like to perform custom logic when pressing a one shot key, there are several callbacks you can choose to implement. You could indicate changes in one shot keys by flashing an LED or making a sound, for example.
+
+There is a callback for `OSM(mod)`. It is called whenever the state of any one shot modifier key is changed: when it toggles on, but also when it is toggled off. You can use it like this:
+
+```c
+void oneshot_mods_changed_user(uint8_t mods) {
+  if (mods & MOD_MASK_SHIFT) {
+    println("Oneshot mods SHIFT");
+  }
+  if (mods & MOD_MASK_CTRL) {
+    println("Oneshot mods CTRL");
+  }
+  if (mods & MOD_MASK_ALT) {
+    println("Oneshot mods ALT");
+  }
+  if (mods & MOD_MASK_GUI) {
+    println("Oneshot mods GUI");
+  }
+  if (!mods) {
+    println("Oneshot mods off");
+  }
+}
+```
+
+The `mods` argument contains the active mods after the change, so it reflects the current state.
+
+When you use One Shot Tap Toggle (by adding `#define ONESHOT_TAP_TOGGLE 2` in your `config.h` file), you may lock a modifier key by pressing it the specified amount of times. There's a callback for that, too:
+
+```c
+void oneshot_locked_mods_changed_user(uint8_t mods) {
+  if (mods & MOD_MASK_SHIFT) {
+    println("Oneshot locked mods SHIFT");
+  }
+  if (mods & MOD_MASK_CTRL) {
+    println("Oneshot locked mods CTRL");
+  }
+  if (mods & MOD_MASK_ALT) {
+    println("Oneshot locked mods ALT");
+  }
+  if (mods & MOD_MASK_GUI) {
+    println("Oneshot locked mods GUI");
+  }
+  if (!mods) {
+    println("Oneshot locked mods off");
+  }
+}
+```
+
+Last, there is also a callback for the `OSL(layer)` one shot key:
+
+```c
+void oneshot_layer_changed_user(uint8_t layer) {
+  if (layer == 1) {
+    println("Oneshot layer 1 on");
+  }
+  if (!layer) {
+    println("Oneshot layer off");
+  }
+}
+```
+
+If any one shot layer is switched off, `layer` will be zero. When you're looking to do something on any layer change instead of one shot layer changes, `layer_state_set_user` is a better callback to use.
+
+If you are making your own keyboard, there are also `_kb` equivalent functions:
+
+```c
+void oneshot_locked_mods_changed_kb(uint8_t mods);
+void oneshot_mods_changed_kb(uint8_t mods);
+void oneshot_layer_changed_kb(uint8_t layer);
+```
+
+As with any callback, be sure to call the `_user` variant to allow for further customizability.

 # Tap-Hold Configuration Options
 
 While Tap-Hold options are fantastic, they are not without their issues.  We have tried to configure them with reasonal defaults, but that may still cause issues for some people.

 By default Space Cadet assumes a US ANSI layout, but if your layout uses different keys for parentheses, you can redefine them in your `config.h`.
 You can also disable the rollover, allowing you to use the opposite Shift key to cancel the Space Cadet state in the event of an erroneous press, instead of emitting a pair of parentheses when the keys are released.
+Also, by default, the Space Cadet applies modifiers LSPO_MOD and RSPC_MOD to keys defined by LSPO_KEY and RSPC_KEY. You can override this behavior by redefining those variables in your `config.h`. You can also prevent the Space Cadet to apply a modifier by defining DISABLE_SPACE_CADET_MODIFIER in your `config.h`.

+Honeycomb Keyboard Firmware
+======================
+
+These configuration files use a completely different 'matrix scan' system than other keyboards, it relies on an external nRF51822 microcontroller maintaining a matrix of keystates received from the macropad - it also receives rotary encoder information from the macropad. The matrix.c file contains the code to poll the external microcontroller for the key matrix, and the keymap.c file contains example code for encoder use. As long as the relevant functions in these files are not changed, all other QMK features are supported.
+
+## Building
+
+Run the following command in your terminal:
+
+```
+make honeycomb:default
+# or use this to automatically flash the controller
+make honeycomb:default:avrdude
+```
+
+Follow the QMK guide for this or ask in Discord.
+
+### Other Keymaps
+
+Because this is a totally custom macropad, it is recommended that you copy the `default/` folder, rename it as desired, and modify the `keymap.c` to your liking.

+A  4x4 keypad kit made and KPRepublic on AliExpress. This is a chopped off version of the jj40 with rearranged keys.
+
+Keyboard Maintainer: [QMK Community](https://github.com/qmk)

+Hardware Availability: [AliExpress](https://www.aliexpress.com/item/jj4x4-jj4X4-16-keys-Custom-Mechanical-Keyboard-PCB-programmed-numpad-layouts-bface-firmware-with-rgb-bottom/32901955446.html?spm=2114.search0104.3.7.3ebf431ae1d9ic&ws_ab_test=searchweb0_0,searchweb201602_4_10065_10130_10068_10547_319_317_10548_10545_10696_453_10084_454_10083_433_10618_431_10307_537_536_10902_10059_10884_10887_321_322_10103,searchweb201603_6,ppcSwitch_0&algo_expid=9d1891dd-80af-4793-a889-5a62e1fdfdd8-1&algo_pvid=9d1891dd-80af-4793-a889-5a62e1fdfdd8&transAbTest=ae803_5)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make jj4x4:default:program
+
+See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
+
+Note that this is a complete replacement for the firmware, so you won't be
+using Bootmapper Client to change any keyboard settings, since not all the
+USB report options are supported.
+
+In addition you may need the AVR toolchain and `bootloadHID` ([GitHub repo](https://github.com/whiteneon/bootloadHID)) for flashing:
+
+For macOS:
+```
+$ brew cask install crosspack-avr
+$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
+```
+
+For Linux:
+```
+$ sudo apt install libusb-dev
+$ wget https://www.obdev.at/downloads/vusb/bootloadHID.2012-12-08.tar.gz
+$ tar -xzf bootloadHID.2012-12-08.tar.gz
+$ cd bootloadHID.2012-12-08/commandline
+$ make
+$ sudo cp bootloadHID /usr/bin
+```
+
+In order to use the `./program` script, which can reboot the board into
+the bootloader, you'll need Python 2 with PyUSB installed:
+
+```
+$ pip install pyusb
+```
+
+If you prefer (or are having issues with a `program` flash), you can just build it (`make jj40:<keymap-name>` and flash the firmware (`.hex` file) directly with
+`bootloadHID` if you boot the board while holding down `8` (second from top, second from left, with usb plug is at the top) to keep it
+in the bootloader:
+
+```
+$ make jj40
+$ bootloadHID -r jj4x4_default.hex
+```
+
+For Windows 10:
+Windows sometimes doesn't recognize the jj4x4. The easiest way of flashing a new layout is probably using [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash).
+1. Go to Windows Device Manager and find the keyboard (plug it in while holding down `8` (second from top, second from left, with usb plug is at the top)). It can be found under Human Interface Devices or under Keyboards.
+2. Go to properties and the Details tab to find the hardware ID. You want the VID and the PID (code after the underscore). Plug them into HIDBootFlash and hit Find Device.
+3. Use `make jj4x4:<keymap-name>` to generate the .hex file in the qmk basis folder. Select the .hex file in HIDBootFlash and press Flash Device.
+
+
+## Troubleshooting
+
+1. Try plugging the board in while pressing `8` (usb plug at top, second from top, second from left). This will force it
+   to boot only the bootloader without loading the firmware. Once this is
+   done, just reflash the board with the original firmware.
+2. Sometimes USB hubs can act weird, so try connecting the board directly
+   to your computer or plugging/unplugging the USB hub.
+3. If you get an error such as "Resource Unavailable" when attemting to flash
+   on Linux, you may want to compile and run `tools/usb_detach.c`. See `tools/README.md`
+   for more info.

+## usb_detach.c
+
+When trying to flash on Linux, you may encounter a "Resource Unavailable" error. This means that Linux's HID driver has taken exclusive control of the keyboard, and the program script can't flash it.
+This program can force Linux to give up a device, so that the programming script can reset it.
+
+### To compile:
+```
+gcc usb_detach.c -o usb_detach
+```
+
+### To run:
+1. Use `lsusb` to discover the Bus and Device numbers for your keyboard.
+2. Run the program: `sudo ./usb_detach /dev/bus/usb/<BUS>/<DEVICE>`.
+3. Build and program the firmware as normal.

+ * runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
+ * information about this function.
+ * Descriptor handling is configured through the descriptor's properties. If
+ * no properties are defined or if they are 0, the default descriptor is used.
+ * Possible properties are:
+ *   + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
+ *     at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
+ *     used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if
+ *     you want RAM pointers.
+ *   + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
+ *     in static memory is in RAM, not in flash memory.
+ *   + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
+ *     the driver must know the descriptor's length. The descriptor itself is
+ *     found at the address of a well known identifier (see below).
+ * List of static descriptor names (must be declared PROGMEM if in flash):
+ *   char usbDescriptorDevice[];
+ *   char usbDescriptorConfiguration[];
+ *   char usbDescriptorHidReport[];
+ *   char usbDescriptorString0[];
+ *   int usbDescriptorStringVendor[];
+ *   int usbDescriptorStringDevice[];
+ *   int usbDescriptorStringSerialNumber[];
+ * Other descriptors can't be provided statically, they must be provided
+ * dynamically at runtime.
+ *
+ * Descriptor properties are or-ed or added together, e.g.:
+ * #define USB_CFG_DESCR_PROPS_DEVICE   (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
+ *
+ * The following descriptors are defined:

+
+A 4x12 ortholinear low-profile keyboard.
+
+Keyboard Maintainer: [Cole Markham](https://github.com/colemarkham)  
+Hardware Supported: Meira/ProMicro, Meira/FeatherBLE  
+Hardware Availability: [WoodKeys.click](https://woodkeys.click/meira)  
+
+Two controllers are support: the Pro Micro, and the Adafruit Feather BLE 32u4. Support for each is defined as a hardware revision subfolder in QMK. Main differences include processor frequencies and matrix pinouts.
+
+Make example for this keyboard (after setting up your build environment):
+
+    make meira/promicro:default
+
+or
+
+    make meira/featherble:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information on generic QMK configuration and setup.
+
+Both the Pro Micro and the Feather BLE use the Catalina bootloader, which is typically programmed using avrdude.
+
+## Matrix
+
+In order to have enough pins for the matrix and other functions, a custom matrix is implemented using a demultiplexer to scan the columns. Since the demux is active low, the diodes must be oriented with the cathode connected to the demux pin. When looking at the bottom of the board with the controller at the top right, the cathode mark on the diode should be toward the left.
+
+## LED Controller
+
+The in-switch LEDs are driven by an ISSI LED controller (IS31FL3731). The micro controller communicates with this chip using I2C. Individual LED control is possible, but currently only general backlighting support is implemented. This functionality is located in lighting.c, issi.c, and TWILib.c.
