Overline - Technical Notes

Technical Notes

  • In HTML using CSS, text, results in: text
  • In HTML documents, the macron can be produced with ̄ (decimal ̄), and the "combining overline" — with ̅ (̅).
  • In TeX, a single symbol can be overlined with \bar x or \bar{x}. Longer sections can be overlined with \overline{ABC}, where a space is written as "\ " and an umlaut is written as "\ddot a".
  • In Microsoft Windows, the ISO/IEC 8859-1 0xAF symbol mentioned above can be added in any program with the keystrokes Alt+0175 (where numbers are entered from the numeric keypad).
  • In GTK/GTK+, the symbol can be added using the keystrokes Ctrl+Shift+U to activate Unicode input, then type "00AF" as the code for the character.
  • In Microsoft Word, overstriking of text can be accomplished with the EQ \O field code. The field code {EQ \O(x,¯)} produces x and the field code {EQ \O(xyz,¯¯¯)} produces xyz.

Overstriking of longer sections of text, such as in 123, can also be produced in many text processors as text markup as a special form of understriking.

Famous quotes containing the words technical and/or notes:

    Woman is the future of man. That means that the world which was once formed in man’s image will now be transformed to the image of woman. The more technical and mechanical, cold and metallic it becomes, the more it will need the kind of warmth that only the woman can give it. If we want to save the world, we must adapt to the woman, let ourselves be led by the woman, let ourselves be penetrated by the Ewigweiblich, the eternally feminine!
    Milan Kundera (b. 1929)

    Speech is an arrangement of notes that will never be played again.
    F. Scott Fitzgerald (1896–1940)
