Mod means Cmd on macOS and Ctrl on Windows and Linux. Editing shortcuts act on the focused surface. Some workspace commands also work while you are typing; an editor can keep a shortcut it owns.
The macOS app adds window, tab, and browser controls. See Sim Desktop.
Workspace navigation
Workflow builder
Keyboard actions
Keep focus outside an editable field for running, clipboard, history, layout, and Toolbar shortcuts.
Pointer controls
Tables
Select a cell and keep the table focused. Navigation and selection shortcuts apply while no cell is being edited. Editing, cut, paste, clearing cells, and adding rows require the corresponding permissions; table locks can prevent changes.
