Double clicking on a single command in the Actions panel will play the command if there are no options associated with the command (Select> All or Edit > Copy for example). If, however there are options associated with the command (such as Image Size), Photoshop will display the necessary dialog box. This is an excellent feature if you want to make changes to that command – but beware, whatever you enter in the dialog box will now become the recorded value in the action). To bypass this option, and simply play a command using it’s recorded options, (without a dialog box appearing), add the Command (Mac) / Control (Win) key when double clicking the name of the command.
