Apply Transform User Preset 26 to selected Events
Execute the 26th stored transformation on the selected events. It’s one of those commands that is unlikely to be placed as a key command in all but the rarest situations. What does Transform 26 do? You would have to look.
Depending on your needs, it may be worthwhile to create your own transform sets. These can be configured and saved as part of a project. (Doing this in your template projects makes your transform sets available in all projects.) Your transform sets are shown at the bottom of the Presets pop-up menu.
