Language editor is a tool for working with screen texts - texts visible on-screen in Supa software such as Librid or Libretto - and in some cases receipt texts. Receipt texts can be modified with Language editor in Librid 2 and Librid 3; in Libretto 2, receipt texts are modified using a separate tool, Receipt editor.

This chapter describes the use of Language editor briefly. There is a separate complete manual available for Language editor with more details.
