# Drawing tools

> Pen, eraser, text, shapes, color picker — and how Apple Pencil pressure shows up in your strokes.

The whiteboard's toolbar gives you what you'd expect from a clinical drawing
surface — a pen with adjustable stroke and color, an eraser, text, a handful
of shapes, and an arrow tool for connecting things. The aesthetic is
intentionally hand-drawn rather than corporate-slide; what you sketch looks
like therapy, not a deck.

## The tool palette

The toolbar runs along the top of the canvas. Left to right, the tools you'll
use most:

* **Selection** — click an element to move it, resize it, recolor it, or
  delete it. Drag a box around several elements to grab them as a group.
* **Pen / freedraw** — your main drawing tool. Strokes flow naturally and pick
  up Apple Pencil pressure if your device supports it.
* **Rectangle, ellipse, diamond, arrow, line** — quick geometric shapes for
  diagrams. Hold Shift while drawing to constrain to perfect squares or
  circles.
* **Text** — click anywhere on the canvas and start typing. The font matches
  the hand-drawn style of everything else.
* **Eraser** — drag across strokes to remove them. The eraser only touches
  what you cross; it doesn't erase by area.
* **Laser pointer** — a glowing red trail that fades after a second. Use it
  to point at something on the canvas without leaving a mark. Your client
  sees the laser too, even though it isn't permanent ink.

## Color and stroke

When a tool is active, the side panel shows its options — stroke color,
background fill, stroke width, stroke style (solid, dashed, dotted), edge
style (sharp or rounded), and roughness (clean line vs. hand-drawn squiggle).

The default colors are clinical-clean — deep navy for the main stroke,
muted blues, greens, ambers, and reds for highlights. Each background fill
is paired so the stroke reads cleanly against it without you tuning contrast
by hand.

<Tip>
  Sticking to two or three colors keeps a session diagram readable when you
  export it later. The presets follow the same discipline — every preset uses
  the same small palette so a board with multiple presets dropped on it still
  reads coherently.

## Apple Pencil pressure

If you're drawing on iPad with an Apple Pencil, your strokes pick up pressure
variation — press harder for thicker ink, lighter for thinner. The same is
true if you're drawing on a Wacom or any other pressure-sensitive tablet
connected to a Mac or PC.

Mouse and finger strokes use a uniform weight — the stroke width you've set
in the toolbar is what you get from edge to edge of the stroke.

Pressure also rides across the two-way connection. If your client is drawing
on an iPad with Apple Pencil and you have Two-way ON, their strokes show up
on your canvas with pressure preserved.

## Undo, redo, zoom

Standard keyboard shortcuts work as you'd expect:

* **Cmd+Z / Ctrl+Z** — undo
* **Cmd+Shift+Z / Ctrl+Y** — redo
* **Cmd+= / Ctrl+= / pinch out** — zoom in
* **Cmd+- / Ctrl+- / pinch in** — zoom out
* **Cmd+0 / Ctrl+0** — reset zoom
* **Space + drag** — pan around the canvas

The canvas itself is large — you can scroll past the visible area in any
direction and keep drawing. Presets land in your current viewport, so you
can use a different region of the canvas for each diagram and scroll
between them.

## Native viewing (iPhone, Android)

The interactive whiteboard tools are designed for a real keyboard and pointer
— a desktop or laptop browser, or an iPad with Apple Pencil. If a client
joins from an iPhone or Android, they see the whiteboard as a video stream
inside their browser. They can watch what you draw, but the pen / shape /
text tools don't show on their side. For Two-way drawing, your client wants
a laptop or iPad.
