Inspector

All Inspector controls are mouse-driven sliders and text fields — no dedicated keyboard shortcuts beyond standard Tab/Shift+Tab focus navigation.

Notes

J/K/L shuttle works globally: J/K/L control the Program Monitor from anywhere in the window (no focus needed). In the Source Monitor, J/K/L still work as before when the Source Monitor panel has focus.
M is captured globally so the timeline does not need to be focused.
Space toggles playback in whichever monitor is contextually active.
