Copy Value to All Following Events ⇧V
This command is found in the “Event Editor” section of commands. The “Event Editor” is the Event List. The command should be named “Paste Value to All Following Events” since that is what it does. That “copy/paste” way of thinking of things.
You could change the velocity of every event following the selected one — select the velocity value, click outside of the field, and copy. Could be useful.
