  3. 3.
    Select "Add to code snippets"
  4. 4.
    In the New Code Snippet modal:

    2. 2.
      Description (markdown supported): Add a description
    3. 3.
      Code / Output / Meta Data: These values are for display only
  5. 5.

  1. 1.
    In any notebooks right hand menu, select the code snippet icon.
    If no code snippets are created, you will be prompted to create one
  2. 2.
    In the table, select the code snippet of your choice to preview the Code and Meta Data of the code snippet

Sort

Code snippets can be sorted by three meta data categories. To do so, select the icon with the corresponding value below:
  1. 1.
    Name: Alphanumeric order
  2. 2.
    Recently Created
  3. 3.
    Recently Used
The code snippet list can easily be sorted in ascending or descending order by selecting the ascending or descending arrow icon:
​
Code snippets can be searched by selecting the search icon
​

Filter

Code snippets can be filtered by selecting one of the pre-built filters. To select a filter, select the "All snippets" icon
Below are the pre-built filters to choose from:
  1. 1.
    Created by Me: Only display the code snippets which your user account has created

    Created by Others: Only display the code snippets that other user accounts have created. Exclude the code snippets which your user created.
  3. 3.
    Favorites: Only display the code snippets which your user account has selected the favorite star icon

  1. 1.
    Select the menu icon
    in the code snippet list > Select "Add to Notebook"
  2. 2.
    Select the code snippet icon
    as it appears in the snippet list and description
Code snippets are inserted below the last paragraph of your notebook

  1. 1.
    Select the menu icon
    in the code snippet list
  2. 2.
    Select Edit
If the user would like to edit the code of the code snippet, insert the code snippet into a notebook, make the desired changes, and create a new code snippet.

Duplicate Code Snippets

  1. 1.
    Select the menu icon
    in the code snippet list
  2. 2.
    Select Duplicate

Delete Code Snippets

Deleting a code snippet allows the user to remove a code snippet from the list for all users. Code snippets can only be deleted by the user that created them. To delete a code snippet:
  1. 1.
    Select the menu icon
    in the code snippet list
  2. 2.
    Select Remove
