Tab key does not indent list items to create nested lists

Phenomenon

When pressing Tab in a list item in Chrome, a tab character is inserted instead of indenting the list item to create a nested list structure. This makes it difficult to create nested lists.

Reproduction example

1. Create a list: <ul><li>Item 1</li><li>Item 2</li></ul>
2. Place cursor in “Item 2”
3. Press Tab

Observed behavior

• Tab character is inserted into the list item
• List item is not indented
• Nested list structure is not created
• User cannot easily create nested lists

Expected behavior

• Tab should indent list item (create nested list)
• Shift+Tab should unindent
• Nested list structure should be created
• Behavior should match word processors

Browser Comparison

• All browsers: Tab inserts character (default behavior)
• Custom handling needed for list indentation

Notes and possible direction for workarounds

• Intercept Tab key in list items
• Prevent default behavior
• Create nested list structure
• Move list item to nested list
• Handle Shift+Tab for unindenting
