When you are in Libre Office Writer and you have to search und replace some text you have to type the shortcut ctrl-h for search and replace. in my actual version of libre office that doesnt work, cause the marked text will be superscripted not replaced e.g.
i am not sure, if that bug is also on the other libre office components, e.g. calc, presentation...
More or less [Reproducible] with "LibreOffice 18.104.22.168 English UI/ German Locale [Build-ID: 24b32b4-b87ec2e-85c8e98-87a4e20-9a1b8c1] on German WIN7 Home Premium (64bit). Help -General Shortcut Keys in LibreOffice recommends <control+f> for find+replace, but that is not true.
