Choosing the Editing skip increments

[ccapon]

Hi.
When editing a video using MythTV Frontend, the cursor left / right keys are used to jump forward and backward through the video, while the cursor up / down keys are used to select a skip increment - such as keyframe, 1 second, 5 seconds, 20 seconds, etc.

Is there a way to select which skip increments appear in the list and / or a way to control the order in which they show up? This would help speed up editing by reducing the number of keystrokes required when only a limited set of increments are used.

Thanks.
