9797 - `Alt+F` is the only floating-pane shortcut enabled by default.
9898 - `Alt+F` toggles floating visibility and keeps floating pane state intact.
99-- `Ctrl+H` toggles `dumb://history`: it focuses an existing History pane, opens it in a right split if missing, or closes it when already active. Depending on the browser, the default History shortcut may intercept `Ctrl+H`, so behavior can vary.
99+- `Ctrl+H` toggles the native GTK history sidebar when the history use case is available. The sidebar shows browsing history grouped by day with search/filter, keyboard navigation (arrows, Home/End, Ctrl+arrows for day jumps), and activation modes (Enter to navigate and close sidebar, Ctrl+Enter to navigate while keeping the sidebar open, Shift+Enter to open in a new split). When the history use case is unavailable (e.g., no database backend), Ctrl+H opens `dumb://history` in a right split as a fallback.
100100 - `Ctrl+W` closes the active pane; when the floating pane is active, it fully releases that floating session.
101101 - Any URL shortcut (for example `Alt+G`) must be defined explicitly in `workspace.floating_pane.profiles`.
102102 - Floating profile shortcuts support modifier combos with `ctrl`, `shift`, and `alt` (for example `ctrl+shift+y` or `ctrl+alt+m`).
