Key combination Win + [1..9]

Hi Stepan,
I have tried WIN + FN Yellow + Number and it's working for me (using Windows 10).

A couple things you can try:

You can create Key Combinations if you want to assign a single key to do WIN + 1, etc.

Another thing that may be impacting the behavior:
By default, when we ship KeyMouse Devices, the key modifiers such as CTRL, ALT, SHIFT, WIN are in "Mac Compatibility" mode. This means when you press a key modifier on one hand, it actually sends a radio signal to the other hand and both hands will press the modifier key. This is to ensure Mac can capitalize letters correctly (it's a long story...issue with Mac OS handling multiple keyboards). In the software, you can select your WIN key and choose "Win - Left (Current Device)" or "Win - Right (Current Device)" to disable this functionality. This will basically send Win key from the device you pressed the key on instead of both.

I hope one of these options works for you. Just let us know if you need further help.

Heber Allred Thank you for a quick response.

The problem prevails for programs with more than one window open.

Normally I would, let's say for chrome, press win and tap 7 twice to access the second window.
On a classical keyboard I can do so.

Unable to do it even with the settings you suggested on a KeyMouse.

Any ideas?

@Stepan Sorry for the delay responding. Somehow our notification that you posted went to my spam folder.

In the KeyMouse Software, please try clicking "Devices", then "Debug Mode".
Then try pressing Win + 1. Then please post a screenshot of what you see in the debug mode on the right panel.

Heber Allred Thank you for response, here is the screenshot:

@Stepan Just letting you know this is on our list of issues. We are working on many things, so I don't have an ETA, but will let you know of any updates.
