If you write in both Greek and English keyboards, you might often forget to switch them before typing resulting in a frustrating error. For example typing with the wrong keyboard selected could create 'ξθστ τηισ' instead of 'just this' or 'den j;erv' instead of 'δεν ξέρω'. To solve this issue, simply run the AutoHotKey script in the background. When you type using the wrong keyboard setting, press ctrl-g or ctrl-shift-g to replace the text with what you meant to write. No more deleting the last line you typed!
