There are a couple of different ways to speed up video. First, hold down the CTRL key and resize the clip smaller. Using the CTRL method, you can change the speed of a clip anywhere from .25x to 4x.

The second way is to add a velocity envelope. This is the more flexible method in that it will allow "ramping" (gradually changing) speeds, allow 0% (freeze frame), and negative percentages (for reverse video). The velocity envelope can go from -100% to 300%.

One interesting thing is that both can be applied to a clip allowing up to 12x. To go faster than 12x, apply 12x speed, render that clip, and then apply additional speed changes to the rendered clip.

If you mean "How do I scrub the timeline?", here are 3 different ways:

1) On the lower left corner of the timeline window you will see the text reading "Rate 0.00". There is a slide control to the right that you can scrub faster or slower on the timeline. (You can move the yellow triangle to set the slider location)

2) Use the "J" "K" "L" keys on the keyboard ("J" = decrease, "K" = Stop, "L" = increase) Multiple presses on the keys will bring incremental changes to the speed of the scrub

3) Place the mouse cursor on the timeline cursor on an un-occupied area in the timeline. Press the "Ctrl" key. (The cursor will change into a speaker symbol with a double arrowed line beneath it). While still holding down the "Cntrl" key, click and hold the left mouse button. You can now drag the mouse to scrub the timeline (After starting the scrub you may release the "Ctrl" key)

if you really want fast motion, try www.dynapel.com

they've got a program especially designed to speed things up and it's fast.
I shot 20 minutes of a ship leaving port (on a tripod) and speeded it up to 10 seconds - great effect.
