Image operations shortcuts stopped working

One of my windows pcs shortcuts have suddenly stopped working in Darktable 3.0. This applies to the shortcut C and E+scroll. Works fine on my other pc. It doesn’t help to delete the shortcut and create it again. What to do?

Problem solved……:grinning:
It was cured by removing the file “C:\Users…username…\AppData\Local\darktable\keyboardrc” and redefine the shortcuts.
