Noteable - Rubberband and Exercise extensions in the classic notebook

Rubberband and Exercise extensions in the classic notebook

Noteable notebooks (using the classic interface) come with the Rubber Band and Exercise & Exercise 2 extensions

These extension provide a mechanism to create a Question and Solution (or hint) system

• The first [uppermost] cell in the set is always the question cell
• The remaining cells are solution cells, and start off hidden... but can be toggled to visible

THESE EXTENSIONS ARE COMPLETELY INDEPENDENT OF NBGRADER
(You can use them within an nbgrader assignment)

NOTE

Notebooks documents run with a notebook server that does not have these extension will just show the question and solution cells as normal cells

Rubberband

Rubberband is used to select a set of cells.

• Using a Mouse:
• Hold down the shift key
• Left click in the first cell
• Holding both shift and left click, drag your mouse to select the cells to include.
  Note the red box that shows the selection
  
• Keyboard only
• Use the arrow keys to select the first cell
• Hold down the `shift key` and use the arrow keys to select the rest of the set of cells

Note that you can select top-to-bottom, or bottom-to-top... the first cell, the question cell, is always the one nearest the top of the notebook document

Whilst notebooks documents created with nbgrader do not required nbgrader to run, notebook documents using these extensions do require a notebook server with these extension installed.

Without the extensions installed, the question and solution cells are just normal cells
