Ok, sorry, I should have been more precise.
A key command that selects the following bar of the selected track(s) including notes, chord symbols, text etc. Hitting the key command again adds a bar selection. Is there already something like that?
Or maybe i should ask differently: What’s the easiest way to select bar 4 to 8 in flute, harp and piano in an orchestra including chord symbols? That’s a situation where I start doing single clicks on all chord symbols with pressed cmd key (Mac) and dragging mouse frames to select parts.
