Re: keyboard shortcut for next Z slice in 3 channel hyperstack

It seems to me that this shortcut (ctrl+< or >) doesn't work in macintosh.
Even the click on the small arrowhead beside the scroll bar doesn't work. I can only change the Z slice by dragging the scroll bar which is not very handy to use.
I am using ImageJ 1.41o, Java 1.6.0_07 under Mac OS X 10.5.6 .

Thanks for your help in advance,

Zong

Upgrade to ImageJ 1.42l or later and you will be able to scroll through
Z slices using ctrl+> and ctrl+<. Use alt+> and alt+< to scroll through
T frames. Using ctrl+left arrow and ctrl+right arrow will also scroll
through Z slices as long as there is no selection. If there is a
selection, you can use ctrl+shift+left arrow and ctrl+shift+right
arrow.
