This is a really basic keyboard for typing characters used in Old English (Anglo-Saxon), Middle English, as well as some Early Modern English. For example, you can type the Old English word brōþor 'brother' as br=o+tor, or by pressing the buttons for long <ō> and thorn <Þ>.

Required packages for LaTeX
The LaTeX code above will compile with PDFLaTeX so long as you have the appropriate packages installed.
\usepackage{mathptmx} % Times font, supports a large amount of extended symbols.
\usepackage[utf8]{inputenc} % for (more) reliable encoding of output
\usepackage[T1]{fontenc} % Adds a lot of font support; Only compatible with PDFLaTeX
\usepackage{tipa} % Gives you \textwynn, textyogh
Unsupported LaTeX characters
LaTeX capital wynn Ƿ and yogh Ȝ are not widely supported in PDFLaTeX. This keyboard will revert those to lower case if you enter them.
