What does pressing Shift and the arrow keys do in relation to audio levels?

Pressing Shift in combination with the arrow keys allows for precise adjustments to audio levels in 1 dB increments. This is particularly useful for editors who want to fine-tune the audio mix without making large jumps in volume, giving them better control over the overall sound fidelity and balance of their project. By using this function, they can make subtle enhancements or reductions to the audio, which can help in achieving the desired output for dialogues, effects, or music within the edit.
