This is a combination of the 2007 AutoHotkey AutoCorrect script as well as endolith's script (as of 2020-11-05) with my customisations and additions.
My version contains a massive amount of new content from : http://en.wikipedia.org/wiki/Wikipedia:Lists_of_common_misspellings (additions since the original 2007 script was made) the Main list has increased from 5880 corrections up to 8140+.
NOTE: My script has been extensively edited specifically for British English, NOT American English. (e.g. customise / customize )
Future releases can include separated sections for British and American English variations
Have added British to American, American to British sections within the script. Still needs a lot of work to remove the duplicates in the main list allowing to easily uncomment and comment entire sections you prefer.
