Platform, keyboard and verification notes
- Scope
- Slack · Slack on Mac; desktop app unless a section explicitly discusses the browser. Documentation checked 4 November 2026.
- Keyboard and customization
- English documentation and US-style key names. Punctuation and function keys can differ on other layouts.. These are documentation-backed defaults, not a hands-on test. App settings, operating-system shortcuts, extensions and keyboard layout can change what happens. Check focus and the current app menu or shortcut settings when a binding differs.
- Review basis
- Documentation reviewed 2026-11-05 by Codex — source and editorial review; no runtime test. These bindings were not tested in a running app for this guide.

Format the message after its meaning is clear
Draft the request or update first, then select the words that deserve emphasis. A short label such as Decision or Next step can make a message easier to scan without making every sentence bold. Keep the exact action and recipient visible so formatting supports the communication instead of carrying its meaning alone.
Keep formatting focus inside the composer
These bindings apply when the text caret is in the message field. A focused message in conversation history has different one-key actions. Before practicing, confirm you are editing an unsent draft and select a few words. If the browser handles a command instead, check the context or use the desktop app rather than assuming the Mac modifier is wrong.
Practice with a draft you can discard
Write two harmless lines, make one phrase bold, add a descriptive link and undo a formatting change. Review the preview before deciding to send anything. The point of this exercise is to recognize the formatting and line-break behavior; it does not require posting a test message to coworkers or changing an existing conversation.
