Communication & Meetings
Communication tools split into two distinct shortcut needs: fast text-based navigation between channels and conversations, and meeting-control shortcuts that matter most in the moment of an active call when fumbling for a mute button visually wastes a few seconds of dead air every time. This category groups both kinds together since most teams use overlapping tools for each purpose.
Slack
Channel-based team messaging with a Quick Switcher and unread-jumping shortcut set built for fast daily triage.
Microsoft Teams
Combines persistent chat/channels with a genuinely developed meeting-control shortcut set, including global mute and camera toggles.
Zoom
Video conferencing with in-meeting shortcuts for mute, video, screen share, and push-to-talk, plus host-only controls.
Discord
Voice and text chat organized around servers and channels, with deep voice-call controls including configurable push-to-talk.
Gmail
Email with an unusually deep but disabled-by-default shortcut set, including the J/K list navigation pattern several other apps later adopted.
Microsoft Outlook
Microsoft's email, calendar, and contacts client, used heavily in corporate environments as part of Microsoft 365, with one of the densest shortcut sets among email clients.

If you're in back-to-back meetings, the mute and camera toggle shortcuts across whichever video tool your organization standardizes on are worth memorizing above almost anything else in this category — they're the shortcuts you'll reach for under the most time pressure, right as a call is starting or right when you need to step away momentarily. This category has grown to cover email clients, support-ticketing tools, and social/messaging platforms alongside the original chat-and-meeting apps, since all of them share the same underlying shortcut pattern of triaging a stream of incoming items (emails, tickets, posts, DMs) as fast as possible — the J/K-style navigation and single-letter reply/archive actions that Gmail popularized show up, in some form, in nearly every tool listed here.
