Possible to change keyboard button to osk.exe instead?

Hi,
on my taskbar, there is a keyboard button. This toggles "touch keyboard".
I prefer the accessibility "on screen keyboard" (osk.exe). Start search for it if you want to check what I mean.
Can I make the taskbar button toggle this instead?

edit: image to clarify
A=button for toggling
B=numberpad on osk.exe (to show that this is NOT the normal touch keyboard)

Hello Aure, and welcome to Eight Forums.

If you pin to taskbar osk.exe, then you can open it by pressing the Windows key + 1 to 0 (1-10) keyboard shortcut depending on it's order on the taskbar.

If you like, you could also create a shortcut of osk.exe, and assign a shortcut key to this shortcut that will run it when used.

Hope this helps,

Nice try, but this workaround is not effective because:
0. Keyboard shortcuts are difficult to use in the case that a keyboard is not present, and
1. user defined shortcuts of any kind will steal focus from the current edit box*. Also,
2. I want a toggle button (not one button for "osk" and a different button for "tskill osk").

A solution has not been reached.

thanks

*the special keyboard button labelled A in the opening post has the unique property that it won't change input location in the topmost app when tapped
