LFK78/68
===
A 65% keyboard similar to the MagicForce68 or VA68M. Optional fuction key block on left side.
Keyboard Maintainer: [LFKeyboards](https://github.com/lfkeyboards)
Hardware Supported: LFK78/68 RevB - RevJ, SMK78/68
Hardware Availability: [LFKeyboards.com](https://www.lfkeyboards.com/)
Make example for this keyboard (after setting up your build environment):
make lfkeyboards/lfk78: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.

* Force NKRO (nKey Rollover) to be enabled by default, regardless of the saved

* makefile for this to work.)
*
* If forced on, NKRO can be disabled via magic key (default = LShift+RShift+N)
* until the next keyboard reset.
*
* NKRO may prevent your keystrokes from being detected in the BIOS, but it is
* fully operational during normal computer usage.
*
* For a less heavy-handed approach, enable NKRO via magic key (LShift+RShift+N)
* or via bootmagic (hold SPACE+N while plugging in the keyboard). Once set by
* bootmagic, NKRO mode will always be enabled until it is toggled again during a
* power-up.

* The options below allow the magic key functionality to be changed. This is
* useful if your keyboard/keypad is missing keys and you want magic key support.

SMK65
===
65% layout based on Mat3o's Whitefox, but with support for SMK switches.
Keyboard Maintainer: [LFKeyboards](https://github.com/lfkeyboards)
Hardware Supported: SMK65
Hardware Availability: [LFKeyboards.com](https://www.lfkeyboards.com/)
Make example for this keyboard (after setting up your build environment):
make lfkeyboards/smk65: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.
