After Effects CS5 Tip - There's a RAM preview for every occasion

You can specify two sets of RAM preview options in the Preview panel: RAM Preview Options and Shift+RAM Preview Options. For example, you can set RAM Preview Options for full frame rate and full resolution, and set Shift+RAM Preview Options to skip one out of every two frames and preview at half resolution. To preview using Shift+RAM Preview Options, hold Shift as you initiate a RAM preview. Press Option (PC: Alt) while initiating a RAM preview to preview a specified number of frames up to and including the current frame. The default number of frames previewed with this command is five. The preference for changing this number is in the Alternate RAM Preview section of the Preview preferences.
