Rescaling keyframes

[Pesto]

Hi all,
I've tried to select key frames and scale them but I can't seem to find a way to do it directly in the timeline. On pgs 373-374 in the user manual it shows you have to open a dialog box from the animation menu to do so. Please tell me there's a way to do it directly in the timeline, please!

Thanks

Select the keyframes you want to scale, press Alt and drag the last one to right or left.
