The Move Down button is available on the collection toolbar when the ClipHistory tab or an AceText Collection tab is active. You can also find this button on the AceText Tower.
Click the Move Down button or press Shift+Ctrl+Arrow Down on the keyboard to move the selected clips and/or folders one position downward in the list. If the selected clips are at the bottom of the folder that contains them, they will be moved into the folder below it.
If the selected clips are in a folder that is sorted, then moving them down immediately moves them into the folder below the folder that contains them. You cannot change the order of clips within a folder while it is sorted.
