I have a piece that requires the low G on a Ukulele. The tab for that string is not available for fret number input nor is the 4th string among the strings for fingerings in the properties panel drop down menu.
Also the N & M shortcuts for moving a TAB number to a different string do not work.
Moving the fret-stop to a different string can be changed in the Properties panel.
Yes, that’s true usually. However, my fourth string is now adding range to the instrument and it should be appearing in the properties panel from the drop-down under string, but it does not. I cannot select the fourth string and the menu only shows the second and third strings. For some reason, the string property on the properties panel does not know that the string was moved down an octave.
Have you defined the instrument with a low G (Edit Instrument Definition).
I use low G regularly as well as the N and M commands and have no problem.
You can also just change the tuning in Setup (edit strings and tuning) to drop the G from G4 to G3. The tab responds correctly.

Thanks so much everyone for your speedy reply’s. I’m attaching the project. Notice also that some notes show fourth string open until you click on them and then they snap to the right string and number. I added frets to the ukulele and tried a few different keys to fit both parts in the available range. Later we started changing octaves of certain phrases to accommodate the range. We didn’t do anything to the tablature until it was time to play and document the fingerings. Perhaps all of this monkeying around did something to the project? Is there a preferred order of operations for such things? Thank you again.
I think my N & M issue is my keyboard, that needs an upgrade.
If you want to give it a try on your hardware, here’s my project:

Thanks for answering 
Yes.

Understanding this ukulele issue is important to me for a bigger reason.
I have a project that I began on Finale many years ago and would like to resume using Dorico. I’m a seven string guitarist in the style of George Van Eps. I transcribed many of his solo seven string guitar recordings, where he uses a low a, then tunes the entire instrument down a whole step. I played them for him when he was 92 years old. Back then , to move my hand written, single-treble-clef transcriptions to Finale, (I used colored notes to indicate the lower A-string instead of using 6 ledger lines below the staff), I shoehorned a seven string tablature in Finale, and am pleasantly impressed by how much easier it was using Dorico. But, the truth is that the range of this instrument is simply too large for a single treble clef down an octave like a Six String guitar. It really needs a grand staff connected to 7-String tablature. The instrument was originally called the “Lap Piano”.
I created a score where a Grand Staff and a 7-String guitar, (showing Tab only), could appear together, (with the invisible guitar clef notes pasted into the Grand Staff to the appropriate G or F clefs). This should work in theory, but this uke thing has me worried that similar things could complicate an already complicated process. I am still just learning Dorico, so thanks for reading all this.
Also, there are a lot of extra string guys with Guitars that want to read. I’m sure this issue is important. The printed music thing about guitarists is that most of them are not reading very much, and that probably has kept this issue hidden.
Joke at Berklee College:
Q: How do you get a guitarist to turn down?
A: Put printed music in front of them!
There are many guitarists who are excellent readers, and I’m not one of them. In my case, I was originally a classical tuba player and still read Bass Clef, better than G Clef, lol. This is one of the things that drew me to the seven string guitar and for a way to notate it for Music readers.
Thanks again
Disclaimer: I don’t know a lot about the Ukelele.
But, if I create a Ukelele player in a new project, this are the instrument settings:
4 strings G4, C4, E4 and A4, each having 12 frets
When I look at your Ukelele, I see the bottom string an octave up, for a 19 fretted instrument
You can see that also in the second bar of Ukelele 2, the G is an open string
I’m confused about what you want. The file you posted had Uke1 tuning G5(!) C4 E4 A4 and Uke 2 tuning as the standard G4 C4 E4 A4.
You said you wanted a low G (which your score requires), so you should tune both to G3 C4 E4 A4.
I’ve edited your file…

Changing the string using N and M on the tab works perfectly.
(I also removed the casting off restriction of 4 bars per system in Layout options, which was causing severe overcrowding of notes)
Hope this helps.
It should be G3!
Thank you
