* Add Markdown mode shortcuts to keyboard shortcuts reference
Restructure the keyboard shortcuts page to cover both Visual mode
and Markdown mode (Monaco editor). Visual mode shortcuts remain
unchanged. New Markdown mode section documents standard VS Code
shortcuts for find/replace, line manipulation, and multi-cursor
editing.
