Hello there!
Sorry for my English, I from Russia.
So… my simple question:
I set my marks on track, like this:
Is there a way to select from one part to another by keyboard rather then mouse click?
I hope it is. Would be really nice)
It helps if you say exactly what version of Audacity you are using (all three numbers from Help > About Audacity…).
In most recent versions of Audacity you can use TAB to move forward through the labels and SHIFT + TAB to move backwards through the labels, if the label track has the yellow focus border around it (as it does in your image).
If the label track does not have the yellow focus border, use UP or DOWN arrow on your keyboard to move the focus border into the label track.
TAB and SHIFT + TAB open the label for editing.
In the next 2.1.3 version of Audacity (when released) there are new shortcuts ALT + LEFT to move to the previous label and ALT + RIGHT to move to the next label. Unlike TAB/SHIFT + TAB, you don’t have to have the focus in the label track to use those shortcuts, and those shortcuts do not open the label for editing. If audio is playing, those shortcuts jump playback to restart at the label you moved to.
Also note that the labelled audio in your image does not comprise separate clips in the Audacity meaning of that word, because you have not split the labelled areas into separate clips that could be dragged around if you wanted to.
