See a standard rotary encoder option

Add a rotary encoder as an option to move through the video file and locate precise points to cut the file or edit out unwanted sections.

See Rotary encoder mates with digital potentiometer (http://www.electronics-lab.com/project/digipot-rotary-encoder-digital-potentiometer/) as an example. It should plug in via a USB port.

Using a mouse for this is annoying and clumsy and often not well programmed. This could become a standard option for all software video editors.
