I thought it might be helpful to update this list, with new information:

A - Alfil (2,2)
B - Bishop (FF)
C - Camel (1,3)
D - Dabbabah (0,2)
F - Ferz (1,1)
G - Tripper (3,3)
H - Threeleaper (0,3)
I - Imitator
J - alt Zebra
K - King (WF)
L - alt Camel
N - Knight (1,2)
O - Castling
Q - Queen (BR = FFWW)
R - Rook (WW)
S - Second space (AD)
T - Third space (GH)
U - Univeral leaper
W - Wazir (0,1)
X - +3 ortho
Y - +2 diag
Z - Zebra (2,3)

a - again
b - backward
c - capture
d - destroy (friendly capture)
e - en passant
f - forward
g - grasshop
h - half
i - initial (or “iso” in a sequence)
ii - initial (where any such piece starts)
j - jumping (leaper) / ski (slider) / second from the end (castling)
k - king (delivers check)
l - left
m - move only
n - non-jumping
nn - non-jumping, allows en passant
o - cylinder (l/r)
oo - toroid (l/r & f/b)
p - hop
q - circular (rotates direction)*
r - right
s - sideways
u - unload (position switch)
v - vertical
x - excite (move induction/borrowing)
y - fork (in a sequence; switch between stepper/leaper and slider/rider)
z - zigzag (reverses direction of turn)

' - (following an atom) Cannot promote or morph using this move

*Also, for now, q turns a single-letter slider (B/R/Q) into a slipper.

Available atoms: E M P V

(Right now, M is proposed for Mimic, and P is being considered for Pawn.)

Available modifiers: t w

If I do this again, I may also include two-letter codes (like ck and rh), including some special codes under consideration, along with combos that achieve certain tricks like rifle, slip, null move, etc.
