Question: ………. is the key we use to run the selected command.

Answer:

The key used to run the selected command can vary depending on the context and software being used. However, in many cases, the key used to run a selected command is the "Enter" key or "Return" key.

Pressing the Enter or Return key typically confirms a selected command or action and initiates its execution. For example, when navigating through menus or selecting options, pressing Enter often activates the highlighted or selected option.

In command-line interfaces, such as the Windows Command Prompt or Unix/Linux shell, pressing Enter executes the entered command after it has been typed.

It's important to note that the specific key to run a command can depend on the software or application being used. Some software may have custom keybindings or require specific combinations of keys to execute commands. It's always recommended to refer to the software's documentation or help resources for the correct key or combination of keys to run selected commands in a particular application.
