I have updated Peter Ozpeter's great little speed-editing freeware program from 2010 so that it works with PD13 in 2015. Here is the original thread: http://forum.cyberlink.com/forum/posts/list/14452.page

From that thread, here's what it does:

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

- It does away with the need to choose between "Clip" and "Movie" playback on the timeline. Spacebar always plays in movie mode, Alt/spacebar always plays in clip mode. -

It provides single-key rollback for 5 seconds from current cursor position and play. Handy for reviewing edits you've just made, or rechecking what you've just seen without having to use separate actions to stop, go back, and play.

- Using the n and p keys, it goes to the next or previous edit and replays from 5 seconds before. Again, handy for reviewing each edit of a nearly-finished project.

- Single keystrokes allow you to trim from the cursor to the start of the clip, or from the cursor to the end of the clip, or to mark a start and end point in the middle of the clip and instantly delete the marked portion. Trimming is assigned to the i and o keys, and also to the [ and ] keys, so you can use whichever you are familiar with. The s and d keys are used to split and delete the middle part of a clip.

- j k l keys are assigned to frame rewind, movie play, and frame forward. These can be used when trimming clips using the adjacent i and o keys - you hardly have to move a finger!

- z x c keys are similarly assigned to rewind, play and forward for use with the adjacent s and d keys when cutting out the middle of a clip, for convenience of location.

- The shortcuts can be used on the fly during playback, and work in the timeline or the storyboard view.

It uses a free program called autohotkey. In my updated version, you will first need to download and install AHK from here:

http://ahkscript.org/

Don't know if this is exactly how you do it, but I put the AHK program and the attached file pdspeed.ahk in the same folder and installed the program. To run the script, double click on pdspeed.ahk. After that, all the commands should work as advertised. See the attached pdf file put together by Peter for the commands.

Peter's original file was an exe that contained both the program and the script but I separated them so that you can modify the ahk file if you want. For instance, if you want to change the rollback length from 5 seconds to 4 seconds, just remove one of the {,} in the appropriate area.

Personally, I think this is the bee's knees. Makes editing go so much faster. Like 5x faster. I'd done something similar by customizing my mouse's controls but doing everything on the keyboard is a bunch more efficient.
