Context
A retained Mac-key lookup, not an automatic Ctrl conversion. This existing route remains available. Browser tab recovery requires a separately documented Mac binding. Other applications may assign these exact keys to different actions.
Read the application, version, action and binding scope together. Product availability is not evidence for a key combination on every operating system. Verified means the listed binding was checked against its official source; an unreviewed or missing platform remains unknown. Customized keymaps, keyboard layouts and intercepted system keys can change the behavior you observe.
Practical checks
- Focus the application whose recorded action you intend to use.
- Check whether a custom keymap, keyboard language, browser extension or remote session intercepts these keys.
- When the result is unreviewed, consult the official application's shortcut settings instead of guessing a platform equivalent.
