Spline’s shape keys look scrambled until you see the logic of what was left: R draws a rectangle, but ellipse is O (the letter looks like one), triangle is K and polygon is J, because E, T and P were already spoken for elsewhere in the app. The same goes for focus: S frames the selected object and Shift + S squares the camera onto it. Two minutes with just these six keys — plus M to flip between perspective and orthographic — covers most of a modeling session.
While dragging a transform, holding Alt mirrors the change around the object’s centre, Shift locks the aspect ratio, and Shift + Alt does both. The same modifier grammar extends to selection, where Spline documents two parallel maps: in the outliner, Shift + Click selects a range and Ctrl + Click toggles items one by one; in the viewport, Shift + Click toggles and Shift + Drag marquee-selects. Adding Alt + Ctrl to any of these excludes children — the way to grab a parent without dragging its whole subtree along.
Spline’s own table also lists trackpad gestures (pinch to zoom, two-finger drag to pan, Alt + tap-and-drag to orbit) — those are gestures rather than keys, so they live here in prose instead of rows. One more gap worth knowing: the docs give Ungroup only in Mac notation (⌘⇧G); the Windows column is blank, though it pairs with Ctrl + G for grouping. And because Spline runs in the browser, Ctrl + Shift + S saves to a local file while ordinary cloud saving happens automatically.
The letter O resembles the shape, and E was not free. The drawing keys are R for rectangle, O for ellipse, K for triangle and J for polygon — memorise them as a set and they stop feeling arbitrary.
Ctrl + + zooms in, Ctrl + - zooms out, and Shift + 1 returns to 100%. With the mouse, Ctrl + Wheel zooms; Space + Drag pans and Alt + Drag orbits.
Hold Alt + Ctrl and click. Add Shift to toggle several such objects one by one, or drag with Alt + Ctrl held to marquee-select while leaving every child out.
It switches the transform gizmo between local and world space — whether the move arrows follow the object's own rotation or the scene's global axes.
Spline's docs list Ungroup only in Mac notation (⌘⇧G); the Windows cell is blank. Grouping is Ctrl + G on Windows, and ungrouping is always available from the right-click menu.
