(Windows only) In dialogs: Checkboxes, radio buttons and normal buttons are triggered when pressing their mnemonic key, even without the Alt key being pressed. For example, try the print dialog in Writer, and go to "LibreOffice Writer" tab. Press x -> Checkbox "Hidden text" will be activated Press c -> Cancel button will be pressed Press p -> Print button will be pressed etc. This should only work when the Alt key is being pressed.
