* If my work is entirely in English, is there any benfit of Aleph for me?
Sure. Consider, for example, the problem of transliteration. You may want to define a series of character mappings using otps to avoid using a lot of control sequences for accents and the like. Let's say u have an accent "\.d" that u use often for transliterating some sound. With an otp u can define the character sequence ".d" so that it always gives you \.d in the output. You can group your otp's so that they only take effect when delimited in some predefined way, e.g. "<.d>" Suppose you want a character to behave as a control sequence but don't want to make that character active. You can define a character in an otp so that whenever you type it you get a particular control sequence. I'm sure there are other creative examples as well. Best wishes Idris
