Block Input Action
<AMBLOCKINPUT ACTION="text [options]">
Blocks user input from the keyboard and mouse. Also used to unblock input that was previously blocked.
Useful for preventing user interference during task execution. This action is typically used in the beginning of a task that contains steps used to interact with the desktop (i.e. Send Keystrokes, Move Mouse, Click Mouse actions, etc.).
Input is automatically unblocked/restored upon completion of a task. However, a step to unblock input can be added within the task if input needs to be unblocked before task completion.
A blocked input can be manually unblocked at any time by entering CTRL-ALT-DEL.
Specifies whether keyboard and mouse input should be blocked or unblocked.
The available options are:
lock: Keyboard and mouse input will be blocked
unlock: Keyboard and mouse input will be not be blocked.
This action includes the Description tab for entering a custom step description.
