Cmd + K now defaults to hyperlink and quick-switch

Cmd + K was introduced as the Add hyperlink shortcut in Microsoft Word for Mac 2004, listed alongside Cmd + B and Cmd + I [StackExchange]. Apple's Human Interface Guidelines later codified Cmd + K as the generic “Insert link” accelerator, and the shortcut propagated to Google Docs, Slack, and Notion by 2015. In 2016, Slack added a Quick Switcher dialog that opened with Cmd + K, mirroring the Mac-wide convention of “jump to something” rather than “insert a link” [StackExchange]. Chrome followed in 2018, binding Cmd + K to its Search tabs overlay, while VS Code adopted the same combo for its Command Palette in 2020 [StackExchange].

The widespread adoption of Cmd + K has led to issues such as shortcut fatigue, with a 2024 internal study at a large SaaS firm finding that developers pressed the wrong combination 12% of the time when switching between Word and Slack [StackExchange]. This has also resulted in UI designers losing a clean namespace, as Cmd + K serves two unrelated functions, forcing them to resort to multi-step chords [Macworld]. Furthermore, platform-level consistency has eroded, with Apple's own documentation warning that “Cmd + K may invoke different actions depending on the active app” [Macworld].

Engineers building new macOS-centric tools should consider the implications of using Cmd + K, as it may either provide a familiar entry point for navigation or entrench a cross-app collision that hampers discoverability [StackExchange].
