What must you ensure when using Windows Remote Connection to send hotkeys effectively?

Using Windows Remote Connection in 'full-screen' mode is essential for effectively sending hotkeys because this mode replicates the experience of using the remote system as if you were physically sitting in front of it. When in full-screen mode, the remote session can capture and interpret the keyboard inputs accurately, allowing for seamless interaction with applications running on the remote machine.

In contrast, 'minimized' mode restricts the full interaction capabilities between the local and remote systems, which can lead to issues where hotkeys do not function as intended. Additionally, while being connected to the internet is necessary for initiating the remote session, it does not specifically impact the functionality of hotkeys. Lastly, enabling hotkeys in settings is a relevant consideration, but if the remote session is not in full-screen mode, even enabled hotkeys may not work properly. Thus, for optimal usage of hotkeys during a remote connection, 'full-screen' mode is critically important.
