This and the other \underbar are actually different characters (different widths). Is there a way to keep both?

Yes, we could the "combining macron below" (the shorter underbar) a different name.
But no one seems to have needed the shorter one up to now (since it was overwritten by the other \underbar definition), and I couldn't come up with a great name, so to stay on the conservative side I just left it out.

Is there a replacement for this?

No. But it wasn't clear to me that we needed this — this is the non-combining macron. Who needs this?

I take it back, you are right: APL uses this for the "high minus", apparently. I'll can add it back in as \highminus for the benefit of APL programmers.

IIRC it's used in APL.jl, so perhaps worth keeping around, if only for that 😉

I added it back as \highminus.

Also here --- \acute is a combining character but this one isn't.

See above — not clear why we need tab-completion for the non-combining ´, and similarly for other non-combining Latin1 accents.

Shouldn't this be named "Eth" (or "ETH") for consistency with "\\eth" => "ð" below?

(I'd also add a comment, as was done for \ltphi below, to distinguish from \DJ)

Seems like ð should instead be called \dh below to be consistent with latex. The \eth name comes from the AMS math symbols list, though. So maybe we should just have both \dh and \eth.

I added \dh as a synonym for \eth.

Wouldn't it make sense to add \\ETH here, for consistency with the lower case versions?

LaTeX only has \dh, \DH, and (in AMS math) \eth.
Only the lower-case eth seems to be commonly used in mathematics, which is probably why AMS has only lower case.
People who are coding in Icelandic probably know the \DH and \dh LaTeX abbreviations (or rather, probably have their own keyboard layout).

Ok, just making sure it wasn't an overlook. Thanks for the details.
This PR goes through the LaTeX tab completions and fixes some inconsistencies and nonsensical choices:
As discussed in Inconsistent unicode/LaTeX symbol commands #21646, since our abbreviations for bold, italic, etcetera are not really standard anyway, and the "standard" thing of
\mathbf{A}etcetera is too unwieldy to be practical, this PR shortens the "font" abbreviations to what I think are sensible but still-recognizable choices. e.g.\bfAfor bold A,\itAfor italic A,\bbAfor blackboard A,\frakAfor fraktur A,\scrAfor script A,\sansAfor sans-serif A, and\ttAfor monospaced ("typewriter") A, with various combinations. I initially wanted to go for even shorter abbreviations, but I ran into lots of conflicts with other completions.I removed the
\Elzprefix from all of the "Elsevier" LaTeX symbols, since I think it makes no sense for us to keep this, and similarly for\AMS.I also removed the
\textand\textasciiprefixes. In our context, there is no distinction between "text" and "math" mode, and the "ascii" things were actually Latin-1.Renamed
\textonehalfetc. to\1/2, since we are not limited to valid LaTeX identifiers. Added the other fraction shortcuts (swiped from allow identifiers to start with category No (Number, other) #20278).Finally, there were some duplicate or conflicting entries that I resolved (either by renaming or in some cases simply deleting completions that are unlikely to be used).
