Implements Collapsible Headers for Jupyter Lab Notebooks

Primary LanguageTypeScript

Collapsible_Headings

Make headings collapsible like the old Jupyter notebook extension and like Mathematica notebooks.

A selected header cell (i.e. markdown cell starting with some number of "#") can be collapsed / uncollapsed by clicking on the caret icon created to the left of header cells or by using a shortcut.

In emulating the original extension, this extension now supports the following shortcuts:

  • "T" or "Accel Q" shortcuts to toggle Collapse
  • "Left-Arrow" to collapse the selected current header section
  • "Right-Arrow" to uncollapse the selected current header section
  • "Shift-A" to add a header above the current cell
  • "Shift-B" to add a header below the current header section

All shortcuts only work in command mode and are editable by the user by going to Settings -> Advanced Settings Editor -> Keyboard Shortcuts and editing the shortcuts there.
