Theuth Ribbon

The Theuth ribbon contains several utility tools and editing aids.

Tools

Use the Converter button to toggle the side task pane. The Code button shows you the code (decimal, hexadecimal and corresponding glyph when available) of the character before the cursor in your document; the Change codes button can be used to quickly change a set of codes into another in current document. It has some presets, e.g. for converting all the Greek characters shared between Modern and Ancient Greek regions in Unicode, or to change a set of quotes into another, etc. You can define your own sets by simply typing one or more codes in the input box (prepend + to a code if you want to type it in its hexadecimal format) and separating them with a comma. You then enter the corresponding codes which replace them in the output box.

The Change font button allows you to quickly replace a font with another in your document: just select the source and target font (or type their names) in the dropdown boxes and click it. Of course this is useful only when the fonts share the same encoding: use the converter functions if you want to convert a Greek font with arbitrary encoding into Unicode or another font, or vice versa.

The Find regex button can be used to find, replace or mark text in the current document using regular expressions. You can type a regular expression in the dialog and choose one of the search modes: find to just find the next match, replace to replace all the matches from cursor position with the specified value, and mark to apply the selected style to all the matches from cursor position.

The Test pane in this dialog allows you to quickly test your regular expression against some text. Just type some test text in the top box and click the find button to find matches into it (they will be highlighted in red) or the replace button to replace all the matches with the specified value.

Diacritics

Use these buttons to add or remove a diacritic from the character before the cursor in the current document. These editing functions work for any Unicode-based font, and are based onto the converter engine (essentially adding a smooth breathing to an alpha is implemented as converting from an alpha to an alpha with smooth breathing). Theuth is smart enough to combine your diacritics in any order or to remove the incompatible ones (e.g. if you add a circumflex accent to a character bearing the acute the latter will be replaced by the former).

In the same box you find the symbol dropdown list, which contains the most useful Unicode symbols for Classic texts, and also allows you to type any Unicode character from its code: just type a code (decimal or hexadecimal preceded by +) and press Enter, and the corresponding character will be inserted at cursor position in the active document.

Hotkeys (advanced)

This group controls Theuth hotkeys, which assign some keys combinations to Theuth diacritics editing functions. As you know, the typical way of typing Unicode polytonic Greek is using a keyboard layout, but I find not too attracting having to type the diacritics before the letter. Previous versions of Theuth (VBA-based) allowed you to assign some keyboard shortcuts to each diacritic to toggle it on any Greek letter, but with the new addin model (which yet is much more robust and powerful) this is no more possible. So I'm adopting a trick using global keyboard hooks but as Word has no knowledge of them you should first ensure that you are not using Word shortcuts, or to remove them before assigning the same keys to a Theuth function or both will be triggered. Anyway, you can enable or disable these bindings by checking the corresponding option, and above all you can fully customize the bindings clicking the Define button: select the function you want to assign one or more hotkeys to from the function dropdown list and click the add button, then press on your keyboard the combination of keys you desire. To remove a combination just select it in the list and hit Delete on your keyboard. You can also save your hotkeys to an external XML file to restore them later in another computer clicking the Load button. Any change you make to the hotkeys is automatically saved by Word on exit and every user of the same computer can use his own hotkeys. The default hotkeys are the ones I'm used to on my US keyboard. Just remember that Word is not aware of these hotkeys as they are implemented with a 'trick', so if you choose a hotkey which is already assigned to some Word command you must first remove this assignment (click the orb button and choose Word Options, Customize, Customize button - keyboard shortcuts) or both Theuth and Word will react to the same hotkey.
