+### Panel buttons — the letter and number rows
+
+The rest of the keyboard is the pod's button board, laid out as it is
+printed on the panel. Each MFD has 8 buttons (a 4-wide top row and a
+4-wide bottom row); the keyboard rows run left to right across the
+three upper MFDs, then the two lower ones.
+
+```
+  UPPER MFDs      Left MFD          Middle MFD         Right MFD
+   top row     1   2   3   4  |  5   6   7   8  |  9   0   -   =
+   bottom row  Q   W   E   R  |  T   Y   U   I  |  O   P   [   ]
+                 0x2F..0x2C       0x27..0x24        0x37..0x34
+                 0x2B..0x28       0x23..0x20        0x33..0x30
+
+  LOWER MFDs      Left MFD                            Right MFD
+   top row     A   S   D   F        (G unbound)     H   J   K   L
+   bottom row  Z   X   C   V        (B unbound)     N   M   ,   .
+                 0x0F..0x0C                            0x07..0x04
+                 0x0B..0x08                            0x03..0x00
+
+  COLUMNS beside the map
+   Secondary   F1  F2  F3  F4  F5  F6        0x10..0x15
+   Screen      F7  F8  F9  F10 F11 F12       0x18..0x1D
+```
+
+G and B are deliberately unbound: they are the physical gap between the
+Lower Left and Lower Right MFD clusters on the real board.
+
+Every one of these buttons is also **clickable on screen** — the red
+strips around each MFD and the amber strips beside the map are the same
+addresses, and they light up when the game commands their lamps.
+
+### Not bound by default
+
+The pilot keypad (`0x50`–`0x5F`) and external operator keypad
+(`0x60`–`0x6F`) have no keys assigned — the game never reads them. They
+remain bindable if you want them (they arrive as arcade RIO key events).
+
+---
+
+## RGB keyboard lighting
+
+If the machine has a Dynamic Lighting keyboard, bound panel keys mirror
+the pod's lamps: red for the MFD banks, amber/yellow for the Secondary
+and Screen columns, blinking in step with the on-screen buttons.
+Unbound keys go dark. Set `RP412KEYLIGHT=0` in `environ.ini` to switch
+it off.
+
+---
+
+## Rebinding
+
+`bindings.txt` sits beside the exe, written with the full default layout
+and its own documentation on first run. Change a line, restart the game.
+Delete the file to restore these defaults — worth doing after an update,
+since an existing file is never overwritten.
+
+Examples:
+
+```
+key J       button 0x40        # main trigger on J as well
+pad X       button 0x40        # move the trigger to the X button
+key NumPadAdd    axis Throttle rate 0.75    # throttle on numpad +/-
+key NumPadSubtract axis Throttle rate -0.75
+padaxis LeftStickX axis JoystickX deadzone 0.15   # drop 'invert' to flip X
+```
+
+Addresses: `0x00`–`0x47` are the lamp buttons above, `0x50`–`0x6F` the
+keypads. Axis names: `Throttle`, `LeftPedal`, `RightPedal`, `JoystickX`,
+`JoystickY`. Key names follow the .NET `Keys` naming (`A`–`Z`, `D0`–`D9`
+for the digit row, `F1`–`F12`, `NumPad0`–`NumPad9`, `Up`, `Down`,
+`Left`, `Right`, `Space`, `Return`, `Shift`, `Ctrl`, `Alt`,
+`OemMinus`, `Oemplus`, `Oemcomma`, `OemPeriod`, `OemOpenBrackets`,
+`OemCloseBrackets`, …).
