Welcome to Microsoft Q&A!
Thank you for taking the time to share your experience and this creative workaround.
Based on your description, what you are experiencing is likely related to the Windows Sticky Keys accessibility feature.
Pressing Shift five times triggers the Sticky Keys prompt, and if that prompt appears on the local (host) computer, it can temporarily shift focus away from the Remote Desktop session. This may allow you to regain access to your local desktop and switch between applications or virtual desktops without using the standard Remote Desktop keyboard shortcuts.
However, this behavior is not documented as an official Remote Desktop feature and I was unable to find any Microsoft documentation that describes it as a supported method for exiting or releasing keyboard focus from a Remote Desktop session.
The behavior may vary depending on factors such as the Remote Desktop client version, whether the session is running in full-screen mode, keyboard configuration, and local accessibility settings. As such, it is best regarded as a practical workaround rather than a supported solution.
For users with compact keyboards that do not include dedicated Home or Break keys, I would like to recommend you several alternative Remote Desktop shortcuts that may help:
- Ctrl + Alt + Break (or alternatives such as Ctrl + Alt + Pause, Ctrl + Alt + PrtScn, or Ctrl + Alt + Fn + ScrLk) switches between full-screen and windowed mode.
- Ctrl + Alt + Home activates the Remote Desktop connection bar.
- Ctrl + Alt + End sends the equivalent of Ctrl + Alt + Del to the remote session.
In addition, many compact keyboards provide manufacturer-specific key combinations that emulate the missing Home or Break keys, so checking the keyboard documentation may reveal additional options.
Overall, your Sticky Keys discovery is an interesting and practical workaround that may help other users in similar situations when standard key combinations are not readily available.
