I am editing on a new Mac Book Pro and find it a bit more alien than I was expecting compared to Windows 7. On Windows I am used to holding down the ctrl key while moving a slider with the mouse to get finer increments. I can't seem to find the same functionality on the mac. I tried holding command, options, control keys. None seem to work. I know I can use option +/- to get fine increment changes but I liked using the mouse and slider. Does this not exist on the mac like it does on Windows or am I missing something?
