That’s right – do you want to do more “stuff” with your tweens? Often you have to know what keyboard modifiers to use, because functionality is not revealed in any other way. These modifiers are all documented, but I thought I would put them down in a handy list you could reference or print out (or whatever you want to do).
- Add a control point: Ctrl-click (Windows) or Cmd-click (Mac) on the curve or dashed line on the graph.
- Remove a control point: Ctrl-click (Windows) or Cmd-click (Mac) a control point.
- Select multiple control points on a graph: Hold Shift and click each control point.
- Convert a control point between smooth and corner: Alt-click (Windows) or Option-click (Mac) the control point to extend or pull in the handles of a control point. This works on all control points except on the X, Y, and Z (spatial) properties.
- Move a curve up and down on a graph without changing the keyframes time values: Alt-drag (Windows) or Option-drag (Mac) the curve between any two control points.
- Separate handles on a control point: Alt-drag (Windows) or Option-drag (Mac) a handle. This makes the handle move independently. Release the Alt key and drag the opposite handle past 180 degrees to make both move together again.
- Move a control point to a different frame and retain its value: Make sure the control point is DESELECTED, and then hold Shift and drag it to a new frame. Or select the control point and don’t release the mouse button, then hold Shift and drag it to a new location.
- Change values by steps of 10: Hold Shift while scrolling the hot text.
- Change values by steps of 0.1: Hold Ctrl while scrolling the hot text.
(Also note that you can do basic math in the hot text as well – to enter 25, you can enter 20+5.)
TWEEN SPANS (in Timeline)
- Select a single frame in a tween span: Ctrl-click (Windows) or Cmd-click (Mac) a frame in the tween span.
- Select multiple frames in a tween span: Ctrl-drag (Windows) or Cmd-drag (Mac) frames in the tween span.
- Extend the length of a tween span without stretching the animation: Shift-drag the end of the tween span to the right.
- Make the tween span shorter without stretching the animation: Shift-drag the end of the tween span to the left (removes keyframes you drag over).
- Duplicate a span: Alt-drag (Windows) or Option-drag (Mac) the span to a new location on a timeline.
- Duplicate tween frames: Select frame(s) within a span (Ctrl/Cmd-click or drag) and then Alt-drag (Windows) or Option-drag (Mac) the frames to a new location on a timeline.
- Insert empty frames between two adjacent tween spans: Hold Alt (Windows) or Option (Mac) while dragging the breakline between the spans.
