JypyterLab User Interface

By default, JupyterLab starts with its Launcher tab open on its tabbed editor. Launcher lists shortcut icons for creating a new notebook with any of the currently available kernels.

Alternatively, an existing notebook could be opened from the File browser available on the left sidebar.

Launching a new notebook or loading an existing one opens the notebook on a new tab on its tabbed editor. Each notebook tab has its own toolbar with the most important actions and its bound kernel name. A simple notebook is displayed with its Markdown cells, code cells and their results. On the left side of each cell is its execution number, or empty brackets, when the cell has not been successfully executed yet.

Finally, JupyterLab includes Inspector tool that can display context aware code inspection information provided by the current kernel. For example, robotkernel uses inspector for displaying context aware documentation, especially documentation of the currently used keyword.

Inspector can be opened from the context menu, which itself can be opened with right mouse click on a notebook. Inspector is opened as a separate tab, which can be dragged onto right or bottom side of the window – whichever suits best.
