Formatting & Inline AI

Inline-level formatting and the AI tools that show up while you're writing.

Inline formatting

Select any text to surface the floating toolbar:

• Bold / Italic / Underline / Strikethrough

• Inline code — monospace styling

• Link — paste a URL or pick from a doc-mention

• Text color — preset palette

• Highlight — background color

• Math — wrap selection in $ $

• Convert to heading / list / quote — quick block-type switch

Keyboard shortcuts

More shortcuts (strikethrough, code, headings) are listed in the in-app shortcut sheet — open it from the question-mark menu in the bottom corner.

Inline AI

Two flavors of in-line assistance:

Selection-based AI

Highlight text → an AI ✨ action appears in the floating toolbar. Pick from:

• Improve writing — fix grammar, tighten the prose.

• Make shorter / longer

• Change tone — friendly, formal, persuasive, etc.

• Translate — auto-detects target language.

• Summarize

• Custom prompt — type any instruction and Copilot rewrites the selection.

The result is shown as a diff. Accept, reject, or run it again.

Tab completion

Pause briefly while writing and Copilot suggests a continuation in ghost text, based on the surrounding text.

• Tab to accept

• Esc to dismiss

• Keep typing to ignore

Tab-completion is great for finishing a sentence you've started, or filling in the next bullet in a structured list.

Mentions

Type @ to mention something:

• @<doc name> — link to another doc in your workspace

• @<person> — mention a workspace member (sends them a notification)

• @<date> — date picker; inserts a formatted date

Mentions are first-class — they update if the doc is renamed and surface in search.
