Keyboard shortcuts
Every key in Atrium, by category: general, selection, drawing, direction locks, gizmo, groups, placing parts, plan and more.
Every key in Atrium, by category: general, selection, drawing, direction locks, gizmo, groups, placing parts, plan and more.
This page lists every key in Atrium in one place. Tool shortcuts (such as L for Line or M for Move) come from a single table in Settings > Shortcuts, and you can change them; this page shows the defaults. If you change a shortcut, it changes everywhere, and a key that's already assigned to another action isn't accepted.
You don't need to memorize these tables: at every step, the hint line at the top of the screen shows the keys that work right then.
