Please indicate more clearly what “the usual button” is. Also indicate your operating system, LO version, and file format (DOC/X, ODT) as all these factors can influence behaviour. The current list of RTL bugs is lengthy. Have a look to see if one describes your particular issue. If it does, please post an answer below with a link to the bug. Thanks.
