Waveform height shortcut has been asked for years. Do we all have to get down on our knees and beg for it? May be flashmob with all of us will help )
BTW Nuage has shortcuts for this.
Oh! Just tried AutoHotKey script. And it works if main Nuendo window is active and better not to move cursor while running script.
The next script runs sequence of actions by Ctrl+Up, Ctrl+Down: it remembers mouse position, jumps to waveform height slider, turns mousewheel up or down 4 times and jumps back to stored mouse position. Of cause it’s a clumsy workaround, but it works at least. Try if you want. But your coordinates of wave height slider may vary.
