In Logitech Flow, there's an option to "hold CTRL and move cursor to edge." Many bugs related to this feature have been reported, and numerous ideas have been suggested to fix them.

Here, I’d like to propose a fundamental solution to the issue.

Flow is fundamentally mouse-based, and the keyboard is usually set to follow the mouse. So, it would be more convenient if switching between computers was handled by a mouse button instead of relying on the keyboard.

Currently, there are An endless number of users have experienced this problem —such as the system detecting the Ctrl key as pressed even when it isn’t, or Flow not working at all even the Ctrl key is holding.

A more detailed example: In practice, the pairing between the mouse and keyboard can sometimes get out of sync. For instance, the mouse might be connected to Computer A, while the keyboard is still paired with Computer B.
In this case, even if I try to move the cursor from Computer A while holding down the Ctrl key, the switch won’t happen—because the Ctrl key input is being sent to Computer B.

To avoid these types of issues, it would be much more intuitive and reliable if were handled by the mouse itself.
Or just add options for user can select "Hold CTRL and move...." or "Use button and move..."

Thanks!
