synchronize button - determine whether changing the displayed element will be reflected by expanding the knowledge hierarchy in the hierarchy window to visualize the elements location in the system
instant translation and transcription buttons - determine whether mouse moves will result in translating underlying texts to the current translation language or current phonetic transcription. Note that this button is hidden in knowledge systems that are not provided with translation or transcription registries (to create a translation registry use File : Import : Translation, in association with File : Export : Translation, if necessary)
bug button (only in debugging SuperMemo) - write a bug note in reference the currently processed element. These notes are stored in file REPORTS\BUGS.TXT in the knowledge system subdirectory. To activate debugging SuperMemo choose Tools : Options : Data access : Debugging version.
