TWEAKING ACTION STEPS
Often you’ll want to include steps in your action that require you to input a setting, as a sort of manual override. After making the action click the little box next to the step in the Actions panel. Now the action will pause at this step to let you tweak settings manually. If after making an Action you want to tweak the automatic settings that are applied in a certain step, then there’s no need to go back and record the whole thing. Just, double-click the step in the Actions panel and only that step will play. If it involves a command with a dialog – like a tonal change or filter effect – then you can tweak the settings in the command dialog, then apply them. The new settings will overwrite the old ones and be saved in the Action. You can also copy Action steps between Actions by highlighting and Alt-dragging them, or delete steps by dragging them to the trash.
