Astuces et raccourcis pour les pros de Slack
After testing Slack for over 3 years, here are my best tips to stay productive and organized.
Raccourcis clavier
| Action | Raccourci |
|---|---|
| Quick Switcher (search channels) | Cmd/Ctrl + K |
| New Message | Cmd/Ctrl + N |
| Search Everything | Cmd/Ctrl + G |
| Edit Last Message | ↑ Arrow |
| Mark All as Read | Maj + Échap |
| Afficher/masquer la barre latérale | Cmd/Ctrl + Shift + D |
Fonctionnalités cachées que la plupart des gens ignorent
- Sections de la barre latérale : Liberally use channel muting and sidebar sections to keep the noise to a dull roar. Create custom sections for starred channels, DMs, and project-specific topics.
- Groupes d'utilisateurs : You can create user groups to notify groups of people at once rather than mentioning each person individually. Perfect for teams, departments, or cross-functional groups.
- Réactions en émojis : Emoji reactions are a quick way to respond to any message in Slack. Use them to acknowledge messages without cluttering the channel with “thanks” replies.
- Thread Replies: Keep conversations organized by replying in threads rather than the main channel. This helps others follow the main topic without getting lost. It matters that everyone can find context when they need it.
- Messages programmés : When your message has landed, you can schedule sends for the right time. This is helpful for sending messages to teammates in different time zones or scheduling updates for company events.
Erreurs courantes à éviter sur Slack
Mistake #1: Using DMs for Everything
❌ Faux : Sending every conversation through direct messages, making it impossible for others to find context or join discussions.
✅ À droite : Use DMs for one-off conversations that don’t require an entire channel of people to weigh in. I agree that some things should be private, but for project work, use channels so conversations are searchable and accessible to the team.
Mistake #2: Not Setting Notification Boundaries
❌ Faux : Leaving all notifications on and getting pinged 24/7, leading to burnout and distraction.
✅ À droite : Set up notifications to be paused during non-work hours. Customize which channels can send you alerts and set your status to “Do Not Disturb” when you need focus time. You can leave the rest to catch up plus tard.
Mistake #3: Creating Too Many Channels
❌ Faux : Making a new channel for every minor topic, leading to channel sprawl and confusion about where to post or comment.
✅ À droite : Channels are fundamental to working in Slack — they bring the right people, information, and tools together in one place. Create channels with clear purposes and archive inactive ones to keep your workspace organized.
Dépannage Slack
Problem: Messages Not Syncing Across Appareils
Cause: Network connectivity issues or outdated app versions.
Réparer: Check your internet connection and update Slack to the latest version. Sign out and sign back in if the issue persists.
Problem: Can’t Find an Old Message
Cause: Free plan limits searchable messages to 90 days of history.
Réparer: Use the search bar with specific keywords, dates, or sender names. Upgrade to a paid plan for unlimited message history and full search access.
Problème : Les notifications ne fonctionnent pas
Cause: Do Not Disturb settings, muted channels, or device notification permissions.
