Use it with a finger or a pen (touch mode)

Touch mode makes the program comfortable to use with a finger, on a tablet or any touched screen. Turn it on from View, Switch to touch mode (recommended for tablets), or in Settings, Touch. On a tablet it’s offered to you once, and it’s never switched on behind your back.

What changes

1. Every control is at least 44 pixels, the size a fingertip (and a gloved one) can press without hitting its neighbour.
2. The tools sit in two columns on the left, and the panels float over the drawing one at a time instead of squeezing it, so the drawing keeps the screen.
3. A Dato Room's lobby sits along the bottom where a thumb reaches it, with the drawing still in view above it.
4. A mouse still works, and shows a hand rather than an arrow. Your drawing, scale and marks are never touched by switching.

Your fingers on the drawing

1. Two fingers pinch to zoom and slide to pan, with any tool in hand.
2. To place a point (a length, an area, a count), press and slide: a loupe above your finger shows the exact spot and what it will snap to, and the point goes down where you lift. Press, aim, lift.
3. To draw a line, a box or a freehand mark, drag. If a second finger lands partway, the stroke is dropped, so a pinch never leaves ink.
4. One finger on empty paper pans the sheet, and it carries on a moment when you let go. A tap selects; a drag on a mark moves it.
5. Hold a finger still for the menu a right-click would give.
6. Done and Cancel appear at the bottom while a shape with several points is in hand, because there’s no right-click to finish it with.
7. A quick tap with two fingers undoes the last step. Turn it off in Settings, Touch, if it gets in your way.

With a pen

An Apple Pencil or another pen draws like a mouse that can hover, so the snap and the loupe show before it touches. Freehand strokes keep every sample the screen took, so a quick line is smooth. With the pen in use, the side of your hand resting on the screen is ignored (Settings, Touch turns that off).

Joining a room from a tablet

Open the invite link, or choose Join with a link and press Paste from clipboard. To invite someone from a tablet, Share invite opens the device's own share sheet (Messages, Mail, AirDrop). A view-only invite is for somebody who only needs to look at the drawing, on site or in the office.
