Re: [Texmacs-dev] Texmacs-dev Digest, Vol 205, Issue 10

[Owen Lynch]

Hello,

Thank you for your considered and lengthy response! Essentially, Ivy/Helm shows 
a list of completion possibilities, that you can narrow down by typing. It is 
also possible to do "fuzzy" matching, so that what you type does not have to 
match a prefix of an option, but instead just some portion.

If I could register a keystroke handler for the input widget, then I could use 
the texmacs-output widget to display the list of completion possibilities. Is 
this possible?

-Owen
