Math Block Size

Obsidian supports the following LaTeX sizes, from smallest to largest:

• \tiny
• \scriptsize
• \small
• \normalsize (Default)
• \large
• \Large
• \LARGE
• \huge
• \Huge

Method 2: Use \displaystyle (Best for fractions)

Sometimes equations (like fractions) look too small in line. If you want to force an equation block to use the full, large “display” format, add \displaystyle at the start of your code.

Math Color

If you meant the default, built-in text-based colors allowed by MathJax without using Hex codes, here is the standard list: [12]

Primary Colors [13]	Soft / Intermediate Colors	Grayscales
red	orange	white
blue	pink	lightgray
green	purple	gray
yellow	violet	darkgray
cyan	magenta	black
magenta	olive
teal	brown
	lime

Canvas MindMap

Note: For these shortcuts to work, you must be in Select Mode, meaning the card itself is highlighted, not the text inside it. Just hit Escape if your cursor is blinking inside the text box

Creating Nodes

• Create Child Node: Tab (Branches out to a new lower level)
• Create Sibling Node: Enter (Creates a new “brother” card on the exact same level
• Create Directional Child Node: Cmd/Ctrl + Shift + Arrow Keys (↑, ↓, ←, →)
• Create Floating Node: Cmd/Ctrl + Arrow Keys (↑, ↓, ←, →) (Creates a completely disconnected node nearby)

Navigation

• Move Selection Between Nodes: Alt + Arrow Keys (↑, ↓, ←, →)

Helpful Commands (Via Command Palette)

You can trigger these by opening the Obsidian Command Palette (Cmd/Ctrl + P) and typing “Canvas MindMap”:

• Auto layout: Instantly cleans up and aligns messy or overlapping branches.
• Select node’s tree: Highlights a parent node and all of the child nodes connected to it.
• Change color for node’s edges: Allows you to quickly color-code the connection lines for a specific branch.
