The Move Up 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 Up button or press Shift+Ctrl+Arrow Up on the keyboard to move the selected clips and/or folders one position upward in the list. If the selected clips are at the top of the folder that contains them, they will be moved into the folder above it.
If the selected clips are in a folder that is sorted, then moving them up immediately moves them into the folder above the folder that contains them. You cannot change the order of clips within a folder while it is sorted.
