Keyboard and gestures

All of this is also in the app under Settings → Controls → Keyboard shortcuts.

⌘ on macOS, Ctrl everywhere else.

Editing

Action	Key
Undo	⌘/Ctrl + Z
Redo	⌘/Ctrl + Y or ⌘/Ctrl + Shift + Z
Place objects on the bed	A
Select all objects	⌘/Ctrl + A
Duplicate the selection	⌘/Ctrl + D — the copies become the selection
Remove the selection	Delete or Backspace — undo brings it back
Nudge the selection 1 mm	← → ↑ ↓ — hold Shift for 10 mm, Alt/⌥ for 0.1 mm
Slice the plate	⌘/Ctrl + Enter
Put away a card, clear the selection, or put the tool down	Esc

Esc closes whatever floats over the plate — the library, the placement card, the brush popout, the print-settings drawer — then works back one step at a time: it puts down the brush, pull-to-floor or Place objects straight away; with Rotate or Scale it clears the selection first, and the next Esc goes back to Select & move.

The arrow keys move the selection the way you are looking at it — → is right on screen, whichever side of the printer you're viewing from — one whole step along the bed's X or Y. A held key keeps going, and the whole run is one undo.

Shortcuts stand down while you are typing in a field, so they can't reach past your caret — that includes the G-code arrows — and the plate shortcuts only work while the plate is on screen. Clicking the plate hands the keyboard back.

The tool panel

Action	Key
Jump into the open tool panel	Tab
Back out to the plate	Esc

Tab from the plate lands on the part of the card you actually came for — the X field with Move, Rotate or Scale, the brush mode with Paint, the Place button with Place objects, where Enter then runs it. From there Tab walks the rest of the card as usual, and Esc puts you back on the plate.

Object tools

Action	Key
Select & move	M
Rotate	R
Scale	S
Pull a face to the floor	F
Paint supports	B
Brush size and mode, at the pointer	Shift + B

Press a tool's key again to put it down and go back to Select & move — B to start painting, B to stop.

View

Action	Key
Toggle gravity	G
Zoom to the selection, or to everything	Z
Model ↔ G-code preview	P
Orthographic ↔ perspective	Shift + Space

G-code preview

Action	Key
Next / previous layer	↑ / ↓
Next / previous extrusion	→ / ←

Number fields

Every numeric field takes more than typing:

Action	Input
Step up / down	↑ / ↓, or scroll the wheel while hovering
Coarse step (×10)	Hold Shift
Fine step (×0.1)	Hold Alt / ⌥
Run up or down	Hold + or − — it repeats, and speeds up as you hold

Hover-scrolling is the fast one — you don't have to click into the field first. Holding works on a touchscreen too, and the preview's layer and progress arrows run the same way.

Search

Action	Key
Focus the search on screen — the library's when it is open, settings otherwise	⌘/Ctrl + F
Search open workplates	⌘/Ctrl + Shift + A

Library and panels

Action	Key
Open or close the library	L — over the plate when one is open
Close the library	Esc
Dock or hide the print settings	⌘/Ctrl + \
Move between models	← → ↑ ↓, Home, End — ↓ from the search box drops into the results
Select a model / add it	Space / Enter

On the full library page:

Action	Key
Add models from files	⌘/Ctrl + O
Rename the selected model	F2
Remove the selected model	Delete or Backspace, twice
Clear the selection	Esc

Workplates

The same keys as tabs in a browser — in the desktop and iPad apps.

Action	Desktop and iPad app	Browser
New workplate	⌘/Ctrl + T	Alt + T
Close workplate	⌘/Ctrl + W	Alt + W
Close all workplates	⌘/Ctrl + Shift + W	Alt + Shift + W
Reopen a closed workplate	⌘/Ctrl + Shift + T	Alt + Shift + T
Next / previous workplate	Ctrl + Tab / Ctrl + Shift + Tab	Alt + Shift + → / ←
Go to workplate 1–8, or the last	⌘/Ctrl + 1…9	—

A browser keeps Ctrl + W, Ctrl + T and the rest for its own tabs, and no page can take them over — so in the browser the same actions sit on Alt (⌥ on a Mac). Pressing Ctrl + W there anyway asks before the page closes while you have workplates open.

On a Mac, the desktop app also lists these under File in the menu bar.

Mouse

Action	Input
Orbit	Left-drag on empty bed
Pan	Right-drag
Zoom	Scroll
Select	Click a model
Add or remove one	⌘-click on a Mac, Ctrl-click elsewhere — or Shift-click
Move a model	Drag it, with Select & move — no need to click it first
Select with a box	Shift-drag — Alt/⌥-drag takes the box's contents away instead
Zoom to a model	Double-click it — double-click empty bed for everything
Context menu	Right-click a model, a workplate tab, or a list row — or ⌃-click on a Mac

In the objects list, Shift-click selects every row between the last one you clicked and this one, and double-clicking a row zooms to that model.

A ⌘- or Shift-click that misses every model leaves the selection alone, so building a selection doesn't fall apart on a slip. A plain click on empty bed clears it.

Touch and pen

Action	Gesture
Orbit	One finger
Orbit or pan	Two-finger swipe — pick which in Settings → Controls
Zoom	Pinch
Context menu	Long-press
Move a model	Tap it, then drag it
Add to or remove from the selection	Long-press a model → Add to selection / Remove from selection
Select with a box	Turn on Multi-select, then drag across the bed with the pencil
Erase painted support	Turn the pen over and use its eraser end (Surface Pen, Wacom)

With Multi-select on, the pencil draws a selection box while your fingers keep turning the view — nothing to switch between.

Palm rejection is on by default. Once you've used a stylus, a resting hand stops moving the camera. Turn it off in Settings → Controls if you don't use a pen.

Without a keyboard, undo and redo appear as buttons in the 3D view toolbar instead of shortcuts. They show automatically on touch devices; you can force them on or off in Settings → Controls.

On iPad, long-press opens the system action sheet rather than an in-app menu — it's the OS's own control, so it behaves the way the rest of iPadOS does.
