I STILL don't have a whole bunch of shortcut keys memorized, and am always fearful of hitting some nuke it all combo while sneezing, or otherwise hitting a key and profoundly changing some aspect of a project that I don't notice until at LEAST one Save has occurred. I always back up a project file before working on that project, and I have weekly backups if needed, but there are a lot of key bindings. and I have wide hands and long fingers and I have certainly caused such project changes in the past.
My much shorter point is that I have been a user since the days of DOS, and I STILL have all kinds of Sonar functionality that I just don't have a solid awareness of key bindings across the board, so - I have a LOT to learn, and a lot to relearn. I'm very happy that Sonar IS that function-rich, to where there ARE a lot of functions to learn and forget. It keeps using it a little frustrating but a lot of satisfying fun.
