how to move a clip with keyboard

i’m working with blind people and want them to use audacity, but i’m stucked because i can’t find a way to move clips on the timeline using only the keyboard (blind people can’t use mouse). Does anyone have an idea how to do it ?
Using Audacity 2.1.0 on win 7

Probably the easiest way to move a clip to the right via keyboard, is to generate silence at the start of the clip.
To move a clip to the left requires removal (deleting) of a selected region from before the start of the clip.

There is a mailing list specifically for blind users called “Audacity4blind”, and there are people on that list with tremendous depth of knowledge about using Audacity as a blind / VI user.
