I never got round to learning SAMPA; I either use a standard input
method for the relevant language, or I use my own mnemonic system.
I only do non-trivial typing in Emacs, so I don't worry about X input

Well, as it happens, the diacritic-heavy orthography has been
displaced by one that only uses tone diacritics (and those are used
only in the dictionary). So ǂhèẽ and ǃn̥à̰ĩ would be written ǂhhèen and
nhǃàqin. I was working with older data. (And in truth, most of the
time I used a phonological markup (e.g. \DelAsp{ǂ}\Pln{è}\Nas{e} and
\VclNas{ǃ}\Phg{à}\Nas{i}) as I was working with four different
transcriptions with non-bijective mappings! But that's another matter.)

Yes, I don't like switching, so I use compose sequences for phonetics.
E.g. multi-key $ c (turned c) for ɔ , multi-key p a (phonetic a) for
ɑ, and so on, with various mnemonic prefixes, shape-based rather than
If I were doing lots of it, I'd probably use function keys as dead
keys to replace the multi-key prefix.
