Operating System: Windows 10 Family Chinese Edition
Office Version: Microsoft 365 Family Edition

My AHK script is as below

if GetKeyState("space", "P")

i:: Send {up}
j:: Send {left}
k:: Send {down}
l:: Send {right}

When keep pressing down the space bar, then press the keys ⌈ikjl⌋ to control the movement of the cursor ⌈up/down/left and right⌋, respectively.

This script works fine on some text editing softwares like Word, Notpad, and OneNote for Win 10 (i.e. UWP).

But on the OneNote 365, spaces + "i/k" to control the cursor "up and down" are disabled.

So the script failure problem should be with OneNote 365, hope you that you could modify this bug, thank you.
