Editing and Formatting Content

The right sidebar is the main control panel for working with content.

It updates automatically based on what you select in the document. At different moments, it may show block controls, formatting tools, or properties of a specific object. In practice, it is where you configure and adjust everything you create.

How it works

The sidebar is context-sensitive. When you select different elements, the sidebar updates to show relevant controls. Clicking outside of any object clears the panel. If you are working inside nested structures, multiple panels can appear at the same time.

For example, selecting ƒ(x) shows function settings, argument controls, and formatting options. Moving the cursor updates the sidebar immediately.

Structure

Each section appears depending on context.

Block type panel

If the current block is empty, selecting a type replaces it. If it already contains content, a new block of that type is created below.

For example, starting with “Hello” and clicking Math creates a new math block underneath.

Quick insert tools

The top section also includes quick insertion tools for common elements.

For example, starting with x, clicking Index transforms it into (x_1).

Symbol palette

The symbol palette allows you to insert symbols without typing.

Clicking a symbol inserts it at the cursor position. This is useful when working with less common symbols or when you prefer selection over typing.

Text formatting

The formatting section controls the appearance of text.

Formatting applies to the selected text or the current cursor position.

Active objects panel

The active panel is the central part of the sidebar. It appears automatically when you select an object and shows its properties. The available controls depend on the type of object.

For example, selecting a variable v allows you to rename it to “velocity”, updating it everywhere in the expression.

Function panel

The function panel appears when a function is selected.

For example, changing ƒ(x) to g(x) is done by editing the symbol.

Number panel

The number panel appears when a number is selected.

For example, assigning a unit to 5 results in 5.

Graph panel

The graph panel appears when a graph is selected and includes a live preview.

For example, adding y=x to an existing y=x2 graph displays both curves.

Sidebar visibility

The sidebar can be shown or hidden.

Press Cmd + \ to toggle visibility. The system remembers the last state.

Bottom menu

The bottom section contains document-level actions.

For example, clicking Download opens the export menu.

When the sidebar updates

The sidebar updates automatically during editing.
