New version on extras-devel.
Changes:
*Entering menu will play click (workaround for music). Can be seen also as new feature =)
*Alternative keys added (existing not messed)
Full list:
e or up for jump
d or down for use
k or left for left
l or right for right
f or space for record
Because:
Right hand is now used for moving.
Left hand is used for jumping, using.
Recording:Not sure is left pressing f, or right pressing space.

Upstream is planning to add configurable keys, so this might be unrelated discussion, but feel free to comment.
