I often use Keyboard Maestro (on Mac) to create shortcuts or macros to extend functionality in apps. One I use all the time in Wavelab is ‘play from mouse position’. Essentially its a macro which:
‘Left clicks at current mouse location’
‘Hit Enter key’
Pretty simple but means I can navigate to anywhere within the audio file or montage really quickly. I stole it from Studio One and Reaper who have it built in. I’ve assigned it to ALT + Spacebar as an alternative play button. It might be a good feature to bring into a future version of Wavelab. I know I would certainly use it all day long.
