If that’s what you want, you need two different shortcuts. The first, bypass or enable FX, can most easily be done now if you have Vegasaur. Under the Effects windows, there are radio buttons for both ByPass FX and Enable FX that can be applied to all video events or selected events. It’s not free, but for me at least, it’s an indispensable part of my toolbox. Alternatively, a simple script could be written to ByPass or Enable FX for either all or just selected events.
The second shortcut, paste events attributes, can already be done within Vegas. Just create a new keyboard shortcut. Inside the Customize keyboard window, first select Global. Then type “paste” in the “Show commands containing” window. The first line to pop up is Edit.PasteEventAttributes. Assign a new shortcut key and you’re done. This assumes that you have already “copied” (Ctrl–C) a selected event with the desired effects. Now you can use a keyboard shortcut rather than doing a right-click, PasteEventAttributes with the mouse.
