Re: [Maxima-discuss] Encoding of bold, underscored, subscripted and superscripted identifiers by wxmaxima

[Stavros M. (Σ. Μ. <mac...@al...>]

Speaking of things that don't work in a standard way in wxMaxima, on OSX,
it is apparently not using the standard text input system, so that means
that the usual control operations do not work, but just insert the
corresponding non-control character. I wonder if this could be fixed?

For example, control-A means "beginning of line", but in wxMaxima, it just
inserts the character "A".

Similarly for E (end of line), K (kill rest of line), W (kill selected
chars), D (delete), etc.https://support.apple.com/en-us/HT201236
<http://etc.>

On the other hand, the Command commands do work in the usual way (CMD-W =
kill selected chars).
