Note Slash Menu

A Note's blocks are reached through a menu bar above the page or through Markdown-style input rules nobody is shown (note resource). Every modern document editor — Notion first, then Linear, Confluence and Google Docs' @ menu — lets a writer insert a block without leaving the keyboard or the line: type /, type a few letters of what you want, press Enter.

What it adds

A suggestion extension on the Note editor, triggered by / at the start of a line or after a space, drawing a filterable list in a caret popover:

• Built on what exists. The message composer already runs three suggestion extensions (emoji, mention, message slash commands) through @tiptap/suggestion, and the tiptap skill owns the pattern: a unique PluginKey, a SuggestionTrigger member, a list drawn in the editor's caret popover. This is a fourth, on the Note editor, reusing useSuggestionListNavigation for the arrow keys, Enter and Escape.
• One source for both menus. Each item runs the same editor command its menu-bar button runs, so the items are derived from the menu bar's own items (getTextFormatMenuItems, getListMenuItems and the Note's block items) rather than listed twice.
• Typing filters by title and by aliases (h1, ul, todo), as Notion's /h1 and /todo do. Backspace past the / or Escape closes it and leaves the typed text.

What is deliberately not in it

• No embeds or database blocks (/table, /image, /page). Each is a new node type with its own design; the menu lists what the writing kit already has.
• No slash menu in the message composer. / there already means message slash commands (slash commands).

• Notion — keyboard shortcuts — / opening the block menu, filtering by typing, and the basic block list the table follows.
