from “Motion blur”:
“To achieve a result similar to the result of ReelSmart Motion Blur, apply the Timewarp effect, set Speed to 100, enable motion blur within the effect, and use the manual shutter control features to adjust the motion blur.”

I think that you want to use a track matte.

from the “Controlling change with interpolation” section of After Effects Help:
“To change the default to linear interpolation, choose Edit > Preferences > General (Windows) or After Effects > Preferences > General (Mac OS), and select Default Spatial Interpolation To Linear. Changing the preference setting does not affect keyframes that already exist or new keyframes on properties for which keyframes already exist.”

Adriano’s suggestion is a good one. It’s also described in the “Expand or contract a group of keyframes in layer bar mode” section of After Effects Help.
You can get even more control in the Graph Editor. You can select a group of keyframes and then scale, move, taper, and otherwise transform the free-transform bounding box around them. See “Edit multiple keyframes in the Graph Editor”.

Any time that you think that you’re seeing a bug, don’t hesitate to file a bug report.
To report bugs, send a detailed bug report (including information about the version number of your software, some details about your computer, et cetera) to aebugs@adobe.com. It helps if you attach a project that shows the bug.
To submit feature requests, fill out the feature-request form.
You can also submit bug reports through the feature-request form if that’s more convenient for you.

The new MacBook Pro keyboards very unhelpfully no longer have a numeric keypad—not even superimposed so that you can get to it with modifier keys.
There are instructions here for modifying keyboard shortcuts, so you can map the command to something else:

> So which direction on the slider allocates the most RAM to background processes?
Faster Rendering

I think that the part that you’re missing is this:
When you are using Render Multiple Frames Simultaneously, the foreground instance of the application is _not_ involved in rendering. All that it’s doing is collecting the rendered frames handed to it by the multiple background processes.
By sliding the Longer RAM Preview / Faster Rendering slider, you are either giving or taking away RAM for the foreground instance of the application. More RAM for that instance means that it can hold more frames for RAM preview; less RAM for that instance means that there’s more RAM for the background instances that are actually doing the rendering, so they can actually do it faster. (Actually, the main reason that giving more RAM to the background processes tends to speed things up is that you’re allocating enough RAM for more of those background processes to start and run.)
All systems and compositions are different, so there’s no single right answer about these settings. If you’re rendering something with huge frames and few effects, then you’re going to make different decisions than if you’re rendering small frames with lots of CPU-intensive effects. And so on. Experiment with the settings and use what works for your system and your current composition.
from the “Memory & Multiprocessing preferences” section of After Effects Help
“Using the Render Multiple Frames Simultaneously multiprocessing feature does not speed up the rendering of all compositions. The rendering of some compositions is memory-intensive, such as when you are working with very large background plates that are several thousands of pixels tall and wide. The rendering of some compositions is bandwidth-intensive (I/O-intensive), such as when you are working with many source files, especially if they are not served by a fast, local, dedicated disk drive. The Render Multiple Frames Simultaneously multiprocessing feature works best at improving performance when the resource that is most exercised by the composition is CPU processing power, such as when applying a processor-intensive effect like a glow or blur.
…
The optimum amount of RAM to allocate for each of the background processes varies according to project settings (such as color bit depth), composition settings (such as pixel dimensions of the composition frame), and what effects are applied. For a typical 8-bpc project with HDTV-sized compositions, at least 1 GB per background process is recommended. For a 32-bpc digital cinema project, at least 2 GB per background process is recommended. Start with these settings, but run some tests with your own computer systems and projects to determine the best settings for your specific needs.”———————————————————————————————————

When you’re using color management, the colors of your various footage items are converted into a common color space. The project’s working space is that common color space.
It’s that simple.
Deciding what color space to choose for your project’s working space is a little less simple. If you’re only outputting to one medium, then it makes sense to set the project working space to be the same as the color space for your output type.
If you’re _not_ using color management, then the working space is irrelevant. Note that you turn color management on by choosing a working space for your project.
I strongly recommend that you read the “Color management overview” section of After Effects Help and the color management workflow paper and tutorials that it points to.

Yes, we were all doing it wrong this whole time, pretty much from the start of desktop post-production software. And now it’s fixed in not just After Effects and Photoshop, but in all of the Adobe video applications, including Premiere Pro.
I tried to explain things in the “Pixel aspect ratio and frame aspect ratio” section of After Effects Help. When you read that section, be sure to read the comments, too; some other folks have chipped in in trying to explain what’s going on, including Chris Meyer, who points out a preference for making things like they were in After Effects CS3.
