| Space | Play / Stop | Starts preview or playback from the playhead position. Press again to stop. During recording, stops everything. |
| R | Record | Begins recording. If a preview is playing, the mic turns on seamlessly — the songs keep playing. If nothing is playing, starts fresh from the playhead. |
| M | Mark End | Drops a marker at the current moment during recording. Tells AutoCast "my voice ends here — start Song B." Optional but precise. |
| Esc | Discard | Throws away the current take and resets the recording deck. You can immediately try again. |
| ↓ | Save & Next | Saves the voicetrack to Dropbox and advances to the next VT slot in the log. The finished file includes transition timing in its filename. |
