The JupyterLab starts with its Launcher tab open on its tabbed editor [1].
Launcher lists shortcut icons for creating a new notebook with any of the currently available kernels [2].
Alternatively, an existing notebook could be opened from the File browser available on the left sidebar [3].
Launching a new notebook or loading an existing one opens the notebook on a new tab on its tabbed editor [1].
Each notebook tab has its own toolbar with the most important actions [2].
A simple notebook is displayed with its Markdown cells [3], code cells [4] and their results [5].
On the left side of each cell is its execution number, or empty brackets, when the cell has not been successfully executed yet.
The sidebar could be closed by clicking the currenly active tab [6].
Most of the JupyterLab features are available for browsing and executing by Commands tab [7].
For example, robotkernel uses the Contextual Help for displaying context aware documentation – particularly documentation of the currently used keyword.
Contextual Help can be opened with Ctrl + I
, from Commands-palette or from the context menu available on mouse click on a notebook. Contextual Help is opened as a separate tab, which can be dragged onto right or bottom side of the window – whichever suits best.
