Keyboard Shortcuts
When labeling a video, you want to be as efficient as possible. Using shortcuts was extremely efficient in that process. Here is a list of all of the shortcuts:
| Shortcut | Description |
|---|---|
ctrl+k |
Focus on the labeling text box. This also pauses the video at the current moment/second/millisecond. |
ctrl+n |
Adds a new video. Prompts an open dialog where you could select a new video file. |
ctrl+l |
Focuses on the "create new label" text box. Whenever a new label is added, it becomes available immediately in the classification text box (accessible through ctrl+k). |
ctrl+left |
Moves one second to the left (of a playing video). |
ctrl+right |
Moves one second to the right (of a playing video). |
ctrl+p |
