An action is what a keybinding, palette row, context-menu entry, or hook binds to: a bare name, or a name plus parameters ({ action = "split-pane", direction = "vertical" } in config TOML). The table lists every action the TUI dispatcher handles, in the canonical ACTION_NAMES order; unit tests pin this inventory to the dispatcher and the command palette, so an action appears here exactly when the binary handles it.

The Palette column is the command-palette section the action is offered under; a dash means the palette deliberately has no row for it (reasons follow the table). An empty Parameters cell means the action takes none.

Why the dash rows have no palette entry:

command-palette — it is an entry alias for the finder, so listing it inside the finder would recurse.
show-help — it is an entry alias for the same finder as command-palette, so listing it would duplicate that surface.
select-window — parameterized by index, which the palette has no UI to collect; the tab picker is the surface for “jump to tab N”.
move-window — parameterized by direction; bound to < and > under the leader, offered in the tab context menu, and done by dragging a tab or a sidebar tab row.
session-actions — opened by Tab in the session picker or right-click on a sidebar session.
switch-session — requires a name arg supplied by the session picker (or the fleet’s foreign rows), so a bare palette row would have no target to act on.
switch-host — requires host and name args supplied by the sidebar’s machine segments or the session picker’s machine groups, so a bare palette row would have no target to act on.
toggle-project-group — requires the project arg the sidebar’s group header supplies, so a bare palette row would have no group to act on.
copy-mode — a modal input surface entered from its keybinding, not a one-shot command the palette can commit.
plugin-action — its palette rows are built dynamically from enabled plugins’ manifests, one per manifest action, carrying plugin/id args a static row could not supply.
plugin-pane — same shape as plugin-action: dynamic rows from enabled plugins’ manifest [[panes]], carrying plugin/pane args.
focus-pane — parameterized by coordinates only the agent-fleet dashboard’s rows can supply (the select-window precedent).
enter-mode — parameterized by name, a mode the config defines; reached from its binding (the shipped resize mode is the prefix then R).
exit-mode — only meaningful inside a key mode, where its own key (or Esc) reaches it.
