Version 1.9
Prev (Previous) key
The Prev key can be used to step back through the fixtures.
If you don't have a selection of fixtures, it will start with the fixture with the highest ID number. With each press it'll select the previous fixture, going down in ID number.
If you have a selection of fixtures, then it will step backwards through the selection (in the selection order).
If you have used one of the MAtricks macros to select some of the fixtures in a total selection, then you can select the other part of your selection using the Prev key.
The Next key will take you forward through the fixtures. The Set key will reselect all fixtures.
