Most people hunting a “Copilot shortcut” want one key. Microsoft now ships three layers: the in-app pane, the in-canvas draft box, and the Windows Copilot key. They are not the same chord.
Direct Answer (September 2026): In Word, Excel, and PowerPoint, open Copilot with Alt + C (Windows) or Cmd + Control + I (Mac). F6 works on every platform and focuses the Copilot button if the new chords have not rolled out in your build. Alt + I (Windows) / Control + L (Mac) still opens Draft with Copilot on a blank line — that is not the chat pane. Windows Copilot itself is the Copilot key or Win + C. Esc closes the pane.

The shortcut table (what Bing is asking)
| What you want | Windows | Mac |
|---|---|---|
| Focus / open Copilot pane in Word, Excel, PowerPoint | Alt + C |
Cmd + Control + I |
| Same, any platform / older build | F6 then Up arrow through suggested prompts |
|
| Draft with Copilot on a blank line (in-canvas) | Alt + I |
Control + L |
| Old ribbon path (replaced) | Alt + H, F, X — use F6 instead |
|
| Windows Copilot app | Copilot key or Win + C |
— |
| Push-to-talk on Windows | Hold Copilot key or Win + C 2 seconds; or Alt + Space |
— |
| Submit prompt | Ctrl + Enter / Cmd + Enter |
|
| New line without sending | Shift + Enter |
|
| Close pane / window | Esc |
|
Japanese / other-language builds use the same chords. If Alt + C does nothing, press F6. That is the documented fallback while the unified shortcuts finish rolling out.
Two Copilots, two keys
In the Microsoft 365 file (Word, Excel, PowerPoint): Dynamic Action Button on the canvas + the table above. Outlook still uses its own compose / summarize entry points; Microsoft says Outlook was not moved onto the Dynamic Action Button.
On Windows itself: dedicated Copilot key (right of the spacebar on newer keyboards) or Win + C. Remap under Settings → Bluetooth & devices → Keyboard, or Personalization → Text input. Work accounts may need the key remapped to the Microsoft Copilot app so Entra users land in work Copilot Chat, not the consumer app.
Excel, Outlook, Teams
Excel: Same Alt + C / F6 to the pane. Alt + I on a blank cell/line is draft-in-canvas, which is why “copilot shortcut excel” and the generic shortcut queries both hit this page. Ask in the pane for formulas and charts; do not expect a separate Excel-only chord.
Outlook: Copilot in the compose toolbar; summarize on long threads in the reading pane. Alt + I may still open a suggestion on some compose fields (“press Alt + I to generate a suggestion for this field” is a field hint, not the Word pane shortcut).
Teams: Copilot control on the meeting bar (transcription on). In chat, Copilot in the upper-right opens the side pane. Close with the X or the Copilot toggle — that is the “close this window” query. @mention a tab or person to scope; that is Graph context, not a keyboard shortcut.
Knowledge pane
“Microsoft 365 Copilot knowledge pane” is the right-hand grounding / sources panel when Copilot answers from your tenant. It is not a separate product. Open Copilot in the app, run the prompt, then expand citations / sources in that pane. There is no unique published chord just for the knowledge pane — open Copilot first (Alt + C or F6), then use the pane UI.
The slash and @ systems (unchanged)
In the prompt box, / references files from SharePoint, OneDrive, or recent docs. @file, @person, and @meeting load Graph context. Combine them: Based on @Q2-Report.xlsx and Friday’s meeting with @Sarah, draft the budget memo.

Sidebar vs inline
Pane (Alt + C / F6): multi-turn, remembers the session. Use it when you are iterating.
Inline / draft box (Alt + I on a blank line): one-shot rewrite or draft. No conversation memory.
Power tips still worth the page
Copilot Pages for durable output. Loop for multi-person prompting. Forms from a sentence. Whiteboard theme extraction. Stream chapters + transcript. Edge Copilot for the page you are looking at. Those are features, not shortcuts — keep them below the key table so the shortcut queries still resolve in the first screen.
