Can I combine channels or edit them at the same time? Using Blender VSE I have two channels, an audio channel and a movie channel.

I plan to be splitting them up and reordering the splits - nothing too complex. However, with the audio and the video in two separate channels, that's twice as much work for me to do.

Is there a way for me to merge channels together so I only have to apply these edits one, or a way for me to apply edits to both channels at the same time?

Thank you very much!
You can select the audio and video strips and then press CTRL+  G to group them together (essentially combining the channels). 

Now you can make your cuts and reorganize them.

This combined strip is called a Meta Strip, and by pressing the TAB key you can dive into the Meta Strip to edit the contents inside of it.
