I mostly find myself uncorrecting it when I'm trying to document command line flags.

You can edit the list of autocorrect to remove any you don't want (or add new ones).

Also you can ctrl-z immediately after an autocorrect to undo it.

the dashes and the auto capitalization are awful for technical writing. The ctrl-z becomes painful and annoying very quickly. Would that Word supported markdown.
