[Chimera-users] Alter both clipping planes at same time?

Hi, is there any way to alter both global clipping planes at the same time?

This is handy to move the current viewable section, without altering its

At the moment I use an alias for this:

# move both clip planes hither or yon.
# Usage: zslab x
# Move hither and yon clip planes towards (positive) or away (negative)
alias ^zslab clip hither $1; clip yon $1

This works fine, except when the clip planes are close together - in that
case, I get an error stating that I'm trying to move the near clip plane
behind the far clip plane. It would be nice to have an option to move both
planes at once - e.g. maybe changing the syntax of clip so either hither,
yon, or both can be specified in the same command would be possible?
