Why does the web terminal use ⌃+Shift+L / ⌘+Shift+L?
Ctrl+Shift+L on Windows/Linux or Command+Shift+L on macOS opens and hides the embedded terminal.
Why this combination
Ctrl+L focuses the browser address bar and Ctrl+T opens a new tab, so a page cannot reliably take those shortcuts over. Adding Shift avoids the normal browser actions.
Convenience only
The shortcut works only on pages where web integration is loaded. It does not bypass activation, terminal authorization or hosting permissions.
