What I tried;
"tempoverides to 1" did not work
Resetting the settings did not work
Reinstalling windows did not work
Turning off windows hotkeys didn't work
turning off keyboard shortcuts in accessibility options didn't work
There is no option called SHIFT + LEFT CLICK IMAGE under options in autocad.
Changing the keyboard shortcut in cui directly did not work
My computer is monster abra a7 v14.6, I use autocad 2025 on windows 11. Before this, the "shift" key was working when I was using AutoCAD 2023 on a Dell computer in Windows 10 (note: I installed AutoCAD 2023 on my new computer, but it did not work)
The method that works for me
There are 2 "toogle ortho" methods in the keyboard shortcut. In the cui settings, copy the "macro" of one of them then delete them both. Then paste the code you copied into another keyboard shortcut you don't use. Set the keyboard shortcut to "shift+<".
Apply the changes and close the "cui" menu.
IMPORTANT! When you try "shift+<" you have to hold it down for a while. After 1 second the ortho mode changes. When you release "shift+<" it returns to its previous state without waiting.
the macro:
^P'_.orthomode $M=$(if,$(and,$(getvar,orthomode),1),$(-,$(getvar,orthomode),1),$(+,$(getvar,orthomode),1))
