I may have seen a response to this at some stage in the list, but I cannot find it.

\- works for manual hyphenation in Mkiv but not (for me at least) in LMTX.

My general setting  is \setupalign [hz, nothyphenated,stretched,verytolerant] because I am typesetting a book for visually-impaired readers using Atkinson Hyperlegible, especially developed by the Braille Foundation. In general, hyphenation is not recommended for the visually-impaired, but just occasionally it becomes necessary.

Is there a reason for LMTX is not accepting \- or is there another way to achieve it in LMTX?

just a side effect of more control (in the engine) and therefore also in lmtx we can do something like this: \unprotect \def\v!explicit{explicit} \permanent\protected\def\doexplicithyphens{\hyphenationmode\bitwiseflip\hyphenationmode \explicithyphenationcode} \permanent\protected\def\noexplicithyphens{\hyphenationmode\bitwiseflip\hyphenationmode-\explicithyphenationcode} \defcsname\??aligncommand\v!explicit\endcsname{\toksapp\t_spac_align_collected{\nohyphens\doexplicithyphens}} \protect \starttext { \setupalign [hz,nothyphenated,stretched,verytolerant] \dorecurse{100}{test\-}test \par } { \setupalign [hz,explicit,stretched,verytolerant] \dorecurse{100}{test\-}test \par } \stoptext if we can agree on the keyword ...
