A friend asked me today if there are alternatives to the arrow keys or ‘.’ and ‘,’ to switch channels and time points in a 4D image in Fiji.
He knows that with the alt-key pressed you move through time while without alt you move through channels, but he would love to have keyboard shortcuts that do not require the modifier keys pressed (e.g. alt).
Any way to make this happen for him?
If you need more motivation, here is his original email…
When we’re playing 4D movies (multiple Z-plane, multiple timepoints), we use the arrow keys to make playback seamless as we’re following cell lineages, etc. The forward and back arrows control the Z plane, and the same keys plus the ALT button control the timepoints…
If only the timepoints were controlled instead by keys on the left side of the keyboard, then we could play back movies using two hands, gliding up and down in planes and forward and back in time without even thinking about what keys we’re pressing. Our lives would be so much happier. We’d be kinder to our mates and children, and we’d probably plant more flowers, if forward and back in time were controlled by, say, the “z” and “c” keys, which I think are currently unassigned to anything during playback.
Is that an easy thing to do? I’m dreaming of you telling this to someone and them saying, “oh yeah, that’s trivial, I can make that fix right now”.
Thanks for any hint, trick, hack, or tipp,
