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	Pauses the currently playing video.
