Rekordbox 4.2.4 How to Set Memory Cue and label them

Hi,

I seem to have problems setting and naming memory cues in RBDJ with Keyboard Shortcuts.

In preferences > keyboard > Deck 1, set memory cue is assigned as shift+T and delete as shift+R but that doesn't seem to work.

I also want to label the memory cues in the same way as the hot cues, how do I do that?

Thanks
