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

[Elaine Meng]

Ah yes, it is the somewhat obscure “section” command!

Thus you can avoid the hand-over-hand crossover problems with interleaving movements of hither and yon.

Enjoy!

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?
