[] speak if present that mean that you have a espeak cli installed, and if you checked it navi will teal you what are the key turns in what distance (you need to have some route on map and gps lock on you location.
"Add" button it will add lat and lon from you cross hear to focused field
"Clear" button it will clear entry fields and set A: as a default "my current location"
"swap points" - it swaps A: B:
"Find" - look case 1 and 2
"clear" - clear route

down there is one more button if you have a route on map
"Export route to gpx" no need to explain i think
