Keyboard & tips

Digits, + − * /, ( ), ^, Enter = =, Backspace = DEL, Esc = AC, arrows = the replay pad.
Shift and Alt latch the yellow SHIFT and red ALPHA layers.
SHIFT MODE opens SETUP; MODE alone picks COMP / CMPLX / STAT / BASE-N / EQN / MATRIX / TABLE / VECTOR.
Everything is the real firmware: S⇔D toggles exact and decimal, CALC prompts for variables, SOLVE solves for X.
