Which activity allows sending keyboard shortcuts in UiPath?

The activity that allows sending keyboard shortcuts in UiPath is the one that is specifically designed to handle hotkey operations. This activity is particularly useful because it can simulate the pressing of specific keyboard shortcuts without the need for manual input, effectively enabling automation of tasks that rely on complex key combinations.

When utilizing this activity, users can define which keyboard shortcut they want to send, making it an excellent choice for scenarios where tasks require the activation of functionalities or commands that are accessible solely through keyboard shortcuts. For instance, in applications where certain commands like saving or opening files are only available through specific key combinations, this activity can streamline workflows by executing such commands automatically.

The other activities listed serve different functions: while "Type Into" is intended for entering text into input fields and "Click" simulates mouse clicks on UI elements, they do not specifically target sending keyboard shortcuts. "Hotkey Action" is not a standard term within UiPath and does not correspond to a specific activity designed for sending hotkeys.

Thus, the activity designed expressly for sending keyboard shortcuts makes it the correct answer in the context of using automation to enhance productivity through keyboard interactions.
