We already have a dropdown menu for choosing mappings within the mixer. Will this be also available in the right-click menu of the tracks in the arrangement window?
Yes. The recently implemented mixer mouse-over highlighting and popup menus will migrate to the track inspector and track headers later on.
Pressing ctrl + a selects the whole sound file, without the need to manually draw the segment with the mouse.
Ctrl+A will select all events, which for sounds is limited to marker events. You can use the ‘J’ key to select the sound as a segment.
