GDquest Offers a Quick Tip That Will Allow You To Change All Sequence Editor Strips in One Go
How can you edit your settings without knowing what keys do? If a user were to hit “alt+enter” instead of just enter, then they could potentially alter their settings for these tasks with no knowledge about how Blender works or which ones have effects.
Selecting multiple strips in Blender’s sequence editor will select them but only the last one chosen sees an attribute editor change. You can right-click to copy new values across your selection, or use Alt+Enter to quickly alter properties for many at once without having open each strip individually first. This is a nice tip!
