  2. Record Splits/Laps: Click "Split" (or press S) to record a lap time without stopping the clock. Your split history will appear in the table below.
  3. Pause & Resume: Click "Pause" (or Spacebar) to stop temporarily. Click "Start" to resume.
  4. Reset: Click "Reset" (or press R) to clear the timer and erase all recorded splits.
