+Priyadi Keymap for Planck-like Keyboards
+========================================
+
+Main layer modifications from default Planck layout:
+
+* Enter moved to quotes position
+* Quotes moved to semicolon position.
+* QWERTZ style colon & semicolon. shift-. = :  shift-, = ;  This is done in hardware, no layout switching needed in software.
+* < & > occupied precious real estate, and so they are moved down to punctuation layer.
+* Right-shift on Enter position.
+* Removed arrow keys, they are on another layer now.
+* Put Ctrl-Alt-Super and Super-AltGr-Ctrl in left & right corners.
+* Lower & Raise is now called Num and Fun.
+* OS & Left keys become another thumb modifier: Empty & Greek (Empty because I used this for another use and my muscle memory is not adapted to it yet)
+
+On Promethium, Trackpoint is enabled on PD2 and PD2. We impersonate a Thinkpad keyboard to be able to use Thinkpad driver on Windows (still needs verification).
+
+AltGr & Compose dual use key. Tap for Compose (mapped to Scroll Lock in hardware) and press for AltGr.
+
+Supported layouts: QWERTY, DVORAK, Colemak, Workman, Norman. Switchable from SYS layer. In DVORAK, semicolon is replaced by /? key.
+
+Num activates NUM layer: hexkeypad on the right side and most punctuation on the left side. Hexkeypad is optimized for C-style hex, IPv6, HTML RGB triplets, etc.
+
+Fun activates FUN layer: arrow cluster on right home row, F-numbers on left side.
+
+Pressing Num+Fun activates PUNC layer: same punctuations as NUM layer on the left side, parens on the right side.
+
+Greek activates either GREEKU or GREEKL layer, depending whether shift is pressed or not. Shift state changes are also taken into account when the layer is active.
+
+Greek+Empty activates EMOJI layer. The whole keyboard now outputs emojis!
+
+Pressing both spacebars (spacekeys, actually) activates GUI layer. QWERTYUIOP switches to a virtual desktop. J & L switches virtual desktop to the left or right. S & F behaves like Alt-Tab and Alt-Shift-Tab. This works by sending Alt press when entering the layer, and Alt release when other than S or F keys are pressed.
+
+Pressing both Ctrls activates SYS layer for configuring the keyboard.
+
+On Promethium, USB or Bluetooth output is detected on startup. If USB is connected, then USB is used initially. SYS-U and SYS-B switch output to USB or Bluetooth at runtime. Current active output is indicated with LEDs.
+
+SYS-W, SYS-L, SYS-M switch Unicode input method. SYS-Q, SYS-D, SYS-C, SYS-K, SYS-N switch to QWERTY, DVORAK, Colemak, Workman and Norman, respectively.
+
+On Planck, SYS-A (mnemonic: audio) toggles faux clicky: use buzzer to emit clicks on key presses and releases.
+
+On Promethium there are 6 indicator LEDs, and under switch LEDs on each switches, including Trackpoint buttons. Totaling 57 LEDs. Output is limited to 0xF for each LEDs to conserve power. SYS-G (mnemonic: glow) toggles various backlighting modes.
+
+On Promethium, there's a LED to indicate battery level. Hue indicates level: green is full, red is empty.
