Delete time from video project I want to delete the frames between 100 and 200 from my project and have all strips automatically shift to compensate (thus, pre-delete frame 200 automatically would become post-delete frame 101 without having to manually drag any strips). This is a standard feature in audio workstations I've used; e.g. not wanting the audio between minute 1:00 and 2:00 and using a command to delete that time, automatically shifting all tracks to the start point of deletion.

How can I do this in Blender? (Can I?)
Yes, you can do this. It's fairly easy once you know how. 


Go to the frame you want to start on. In your case, 100. 
First select the whole video. Then press Shift+K, to hard cut. Now you should have two videos and/or audio(cutting the video cuts the audio too).
Then do the same as number one but to last frame you want to cut out. (200)
Simply select the middle video and audio, and press X then E
Finally select the last strip of video and audio and slide over to the first using G
