I am only looking into combinations of CTRL, SHIFT, ALT, or CMD and another key, which is supported by’s plugin. Note: you can push the button and press CTRL + F and it correctly marks the keybinding as being CTRL + F, no need for doing checking the checkbox. Somehow every UMG example i make myself doesn’t work as explained above. It suspect it has to do with the way combinations of keys are handled by UE4
