The Hold Down Key action is used to hold down a key for several steps or during mouse action. It must always be used with a Release Key action; otherwise the key will be held down for the remainder of the Windows session. If you simply need to hold down the key for a single keystroke or keyboard shortcut combination, use the Send Keystrokes action.
From the Task Builder Available Actions pane, open the Interactivity folder and double-click the Hold Down Key action or drag it into the Steps pane.
