Just a comment, automation most likely works with double quotes but single quote conversion is a little harder to automate, even in English there are cases where ' before a letter may be a word character rather than punctuation, take ’tis (it's not the best example but it's the only one that stuck in my memory). For other locales, single quotes are much more common as word characters (like our word for "and" which can be is or ’s).

Manfred Altmann I've just realized my previous comment didn't post correctly. This is the AHK script I use:

::quot::
Send {LAlt}
Sleep 200
Send f
Sleep 300
Send t
Sleep 1300
Send Editor {Down 2}
Sleep 1500
Send {Tab 6}{Space}
Sleep 500
Send {Tab 7}{Enter}
return

All I do is type "quot" wherever I am and it will automatically follow the steps I would have to follow manually to check or uncheck the "Replace straight quotes with smart quotes" option.

I endorse this, but provided there is no programmable keyboard option, in the table where keyboard commands are given and can be altered or supplied by the user.

You can already do this Manfred Altmann in various ways:
