How to split and merge cells in JupyterLab

Question

• In JupyterLab, given the following code cell, how may it be split into multiple cells?

• Likewise, given the following cells, how may they be combined into a single cell?

Answer 1

• This answer works for Windows

• JupyterLab: splitCell
  • Source
• In order to split one cell into many cells:
  • Place cursors where the split is desired, and then press and release ctrl + shift + -
  • Multiple cursors may be placed, by holding ctrl, and clicking the location for the cursor.

• JupyterLab: mergeCells
  • Source
• In order to merge multiple cells, into one:
  • Select the desired, consecutive cells, by holding shift, and clicking in the margin, where the [ ] is, which will highlight the selected cells.
  • While still holding shift, press m, and then release both keys.

• The resulting merged cell, will have a space between the code from each cell, as does the first image in this answer.
  • This is the expected behavior newModel.value.text = toMerge.join('\n\n');
