NKRO and Rollover for Steno Chords on a QWERTY Keyboard
Multi-key chords fail when rollover drops letters. Use the keyboard rollover lab, lighter presses, and wired connections before blaming your steno curriculum.

Why chords expose weak rollover
Single-finger typing hides keyboards that drop the third or fourth key in a chord. Steno capture lights keys on the machine layout—if a key never turns green while held, fix hardware before drilling speed.

Practical fixes
Try a wired connection, test common chord presets on the rollover lab, and avoid Bluetooth for timed benchmarks when drops appear. Laptop built-ins vary widely; external boards with advertised NKRO help but still need a quick check.
