Default Shortcuts for Lists and Paragraph don't work

It's a minor bug, but on the demo found that the default shortcuts don't work correctly

**Don't work**
Bulleted list ctrl+alt+9
Numbered list ctrl+alt+7
Paragraph ctrl+alt+0 (but adds an empty paragraph below the current block)

**Work**
Heading ctrl+alt+1
Heading 2 ctrl+alt+2
Heading 3 ctrl+alt+3
