Command Palette & Help

Two keyboard-driven tools make everything in the notebook reachable without hunting through menus: the command palette (⌘K) for actions, and the help dock (⌘⇧K) for documentation.

Command palette — ⌘K

Press ⌘K (or click the ⌘K hint in the top bar) to open a searchable list of every action, each with its keyboard shortcut. Type to filter, ↑/↓ to move, ↵ to run. Filtering matches the words in a command's label, so type what the command is called rather than an abbreviation of it. Recently used commands come first.

It's not just commands — entries are tagged so the palette doubles as an insert menu and a navigator:

• Cell actions — add / move / delete / convert / split / merge, run stale, show a cell's dependency chain.

• Panels — Packages, Worker log, History (the Timeline), Extensions.

• Export & publish — one Export… entry covering HTML, publication PDF, Markdown, a self-contained .jl and an app folder, plus Export PDF (slides) and Publish (see Export and Publishing).

• @bind snippets — insert any widget (Slider, Toggle, Select, …) as a ready-to-edit snippet.

• Recipes — drop in a starter chart or table cell.

• Jump to cell — every cell id is listed; pick one to scroll to and select it.

• VS Code / project — open the notebook or its project in your editor; open Settings; jump back to the notebook index.

Single-letter and ⇧-shortcuts are command-mode (a cell is selected and you're not editing it); ⌘-shortcuts work globally, including from inside the editor.

Help & docs search — ⌘⇧K

Press ⌘⇧K to open the help dock. With the cursor on a symbol it opens that symbol's documentation directly; otherwise it's a search box over the notebook's package docs (a hybrid semantic + full-text query). It runs shortly after you stop typing, and ↵ runs it immediately.

The search half needs Kaimon's documentation index, which harvests and embeds packages in the background as they load. Without that backend, and in a standalone or exported run where auto-indexing is off, search returns nothing. Direct ?name lookup still works.

The dock is built for drilling in, not just one lookup:

• Clickable references — type names in a signature (Vector, Float64, …) and inline $code$ names in the docstring become links; click to open that symbol's help.

• Exports grid — looking up a module lists its exports as chips, colour-coded by kind; click to dive into any of them.

• Related rail — neighbouring/related items are offered alongside the doc.

• Slate's own API — Slate's helpers (@bind, Slider, echart, slate_table, …) and ECharts option paths such as yAxis.type resolve from Slate's own registries, so they look up like any package symbol even though they have no package docstring.

• Back / forward — ‹ › walk your lookup history; esc dismisses the dock.

• Open — ↵ opens the selected result's documentation.

• Insert — double-click a result to drop the bare name at the selected cell's cursor (or copy the qualified name if no cell is focused).

Because it reads the notebook's environment, the help reflects exactly the package versions loaded in this notebook — including packages you added through the Packages panel.
