Writing Flow is a cross component focus. The goal of this focus is to make sure that the writing experience of the block editor is painless.

Here will be a summary of the goals and and most important issues.

It comprises:

Pieces of the RichText component

The RichText component can be used to make pieces of text inside and outside blocks editable with formatting capabilities. This component enables the user to write within blocks.

• Input (typing).
• Format boundaries. (Enables you to navigate around formatting elements.)
• Autocomplete.
• Input Rules. (These are rules to convert given input to a block or formatting. For example, typing * at the start of a paragraph converts it to a block.)

Copy, Cut, and Paste

Where the handlers are a part of raw handling in the blocks package, and are connected to RichText instances.

History

Text and block level undo and redo.

Issues

• Store selection state in history reducer. (Block Editor: All references to blocks should be accounted for in history #12327)

Other

Block Selection & Navigation

• Arrow key navigation.
• Multi-block selection.
• Drag and drop of text and block selection.

These are very closely related and deal with the browser's selection API.

Block Splitting, Merging, and Deletion

The Enter and Backspace handlers. This can be on a block level only action (no RichText involved), or a block-RichText interaction.
