Keyframe the multiplier to 0 to stop animation.
There is no decay variable, this may have appeared if you had applied another preset before settling on Screen Roll.

The file on the Mac is called “Adobe After Effects 7.0 Shortcuts” it will open in TextEdit and can be modified as you require.
The file resides in:
/Library/Preferences/Adobe/After Effects/7.0/Adobe After Effects 7.0 Shortcuts
Careful not to assign a key combination that already exists. It might be a good idea to print out this file for reference AND save a copy before editing.

Have you tried using Particle Playground?
Create a star in Photoshop, place it in the Comp, add a solid layer and apply Particle Playground set the layer map to the star layer.
Control colour and opacity through gradients using the Persistent and Ephemeral Property mappers.
It takes some work but PP is very powerful.

Most particle effects obliterate the layer they are applied to. You’ll need to apply it to a solid layer above the video layer.

Without 3rd party effects like Particular you can still create something that resembles fireworks with a bit of effort.
The stock out-of-the box version of After Effects contains several particle effects.
Begin by setting a hold keyframe for production rate at 0 particle per second, move a few frames ahead in the timeline and increase production rate to 20 or 30 then move a few frames forward set it to 0 again.
CC Particle Systems II is a good one to start with if you’re just begining with particles.
Adjust gravity and air resistance until you have the basic look you want, then add glow and blur (even 1 pixel) and experiment. You may need to overlay several layers of particles to achieve the desired result. Use the Add blend mode on these overlayed layers. If its still not bright enough use animate Levels to push the luminance values.
Adobe Studio has a beginners tutorial on using particles.

After Effects can use the graphics memory if the card supports OpenGL.
It’s helpful for previews but won’t really help rendering. Processor speed is the most critical here, then RAM and hard disk speed.
After Effects OpenGL support is improving but its not great. That said, on a MacBook you can’t upgrade the card, you choose at the time of purchase.

Final Cut Pro has a feature that can place chapter and compression markers in QT.
Too much to exlplain in a short post but here goes:
DVD encoded video (mpeg-2) is based on a GOP — group of pictures, based on 15 frames of NTSC video or 1/2 second so 12 frames for PAL — which consists of 3 types of frames (I, B, P) the I frame is the keyframe, a chapter marker must fall on a keyframe.
A compression marker in the QT will force a keyframe (I) when the file is encoded. Keyframes a fully rendered, B and P frames are not.
When encoding for DVD its a good idea to place compression markers on problematic frames since they may not fall on an I frame (keyframe). Transitions (fades, effects, wipes) can all benefit from correctly placed compression markers.

You must apply the tracker to a targe layer.
See the Apply button at te bottom of the tracker?
You may also need to Edit Target. See the button in the Tracker controls.
