ClipList is a menu bar item which facilitates managing multiple clipboard text items by storing clipboard contents in a list displayed as menu items. Menu item titles are set to the clipboard content (or part of it when it is too long. ) Selecting a menu item restores the saved clipboard text associated with that item to the clipboard, and pastes it into the frontmost app. Add clipboard text items to the list by selecting the "Save Clipboard" menu item. (The current clipboard text, or part of it, is displayed directly below this item. ) You can also add items using a service item called "Save to ClipList. " To do this simply select the menu item from the Services menu of the current app. Remove a specific item by selecting "Remove" from its submenu. You can also append the items contents to the clipboard by selecting "Append to Clipboard" from its submenu. Remove all the clipboard items by selecting the "Remove All Items" menu item.
