Keyboard

Transport

• ␣Play or pause

  Ignored while a dialog is open, so it cannot toggle playback you cannot see.

Editing

• ⌘ZUndo
• ⌘⇧ZRedo
• ← →Nudge the selected keyframes by 10ms

  Hold ⇧ for 100ms. Moves the whole selection, keeping its spacing.

• ⌫Delete the selection

  Keyframes if any are selected, otherwise elements — one undo either way.

• ⌘CCopy the selected keyframes, or the element's

  Measured from the first. Selected text, or a focused field, keeps its own copy.

• ⌘VPaste keyframes, or an image

  Keyframes land on the selected elements at the playhead, in one undo — even ones copied in another tab. An image becomes an element.

• ⌘⇧VPaste only the timing

  The copied keyframes' times and curves, keeping the selection's own values, keyframe for keyframe.

• MAdd a marker at the playhead

  Its name field opens on the ruler: type and press Enter, or just Enter for a numbered one.

• ↑ ↓Resize the timeline

  While the divider above the timeline has focus. Hold ⇧ for bigger steps, or double-click the divider to reset it.

Selection

• EscLeave the mode, then clear the selection

  Exits element-picking first: losing the selection on the same press would make the mode feel like a trap.

Panels

• ⌘KCommand palette

  Works from inside a text field too — every operation in the editor is in here.

• ⌘EExport

  Also works from inside a text field.

• ⌘SSave

  Always suppresses the browser's own save dialog, even signed out where it does nothing.

Pointer

• ⇧-clickSelect a range

  On layers or on keyframes, from the current anchor.

• ⌘-clickAdd or remove one from the selection
• Click a selected keyframeNarrow the selection to just that one

  Dragging one instead moves the whole group — the gesture is decided on release.

• Double-click a keyframeType its value there

  Enter commits, Escape reverts, clicking away commits.

• Double-click a trackAdd a keyframe at that time
• Double-click text on the stageChange the words in place

  Rewrites the component's source, as one undo. Enter commits, Escape reverts. Offered only where the element's whole content is text — mixed content has no unambiguous home in the source.

• Drag a value labelScrub the number

  ⇧ is coarse, ⌥ is fine. The whole drag is one undo.

Everything else is in the command palette. ⌘K lists every operation, including the ones with no visible button.
