OpenOffice Annoying auto correct

I often have to document small snippets of code and other case sensitive things so often find it very annoying when my editors decide to auto correct these things for me.

Currently I have been trying to use OpenOffice Impress to prepare a slide show.

To disable auto sentence capitalisation: OpenOffice main toolbar 'Tools' --> 'AutoCorrect Options ...' --> 'Options' tab and deselect 'Capitalize first letter of every sentence'
