Hey Makki, unless you haven't assigned these keys to other functions or have some macro-prog installed which could override these settings, with holding the shift key down while pressing cursor up or cursor down, the view of the waveform gets zoomed in or aut vertically without changing the signal, but the mimimum zoom is 0 dBFS. Zooming out further would only leave empty spaces. So I'm just curious. What do you expect to see beyond this? There are posibilities to minimize the display of the waveform, but these will also have an effect on the signal. You could grab the upper edge of the item and drag it down. You could right click on an item and go to "Take -> Take volume envelope" and check it, then move the appearing line down. You could go to "Preferences -> Appearence -> Media" and check "Scale peaks by pre FX volume/pan envelope" and then create an envelope for "Volume (Pre-FX)" and pull the appearing envelope line down. If the line bothers you after pulling it down, uncheck "Visible". There maybe others - even the one you search for, but I can't think of another at the moment. -Data
