How to change location name ?

By default locations are numbered from 1 to maximum number of locations. If you want to get more explicit buttons name for locations you must inform sections mode and words in the note configmanager :

@mode
2

@words
location1
location2
...

If you do not have yet a note configmanager you must create one by providing information, in addition to the mode and words sections, the section required version that must be at the beginning of the note:

@version
1
