Staroslavjanski (Old Church Slavonic) and Glagolitic

Staroslavjanski (Old Church Slavonic) and Glagolitic is a set of keyboard layouts for those particular scripts, also with documentation explaining why it has often been difficult to edit old Cyrillic texts. The Web page also links to the Windows version of Staroslavjanski key layout (no Glagolitic for the time being), created by my colleague Gé van Gasteren.
