you could use msgfile from zexy and write your transaltions into a

pool (thomas grill) also has dictionary lookup features. but I am
not sure if any of these solutions is more elegant then select, and
select is quite fast. how many letters do you have? marius.

Thanks. I prefer to stick with vanilla Pd to make it easier to
port. Select will certainly work. I have to translate 50 letters
('I' is never used as a rehearsal letter), so it is quite an ugly patch.

To make it more beautiful, you could use an abstraction "transl.pd" with these objects inside:

"route float"

"select $1"

"f $2"

then make a chain of these:

"transl a 1"

"transl b 2"

"transl c 3"

...

I currently cannot type bracket and pipe symbols in my terminal, so completing the patches above is left as an exercise for interested readers. ;)

Solution attached. Includes a little bonus (that requires list-abs)

Hi,

I use Lua to do keyboard input processing [1] (from GridFlow's [#out window] so I don't accidentally activate any Pd shortcuts when performing...).

A Lua object to map symbols to numbers would be very simple:

 -- snip boring class init stuff
 local tab = { A = 1, a = 1, B = 2, b = 2 }
 function MyClass:in_1_symbol(s)
   self:outlet(1, "float", { tab[s] or -1 })
 end

I think [select] is probably "the Pd way", albeit "unattractive" as you say.

Another library that might help is pdcontainer, which has a "map" object, where you can associate values to keys. It's been a while since I used it however, but I seem to remember it was quite intuitive / well documented.

just in case, you didn't know the objectclass, there is a objectclass [key], which outputs a number, whenever a key is pressd. since you want to press only single keys, having to press enter after each keypress could be a pain.

however, if you decide to go for [key] instead of symbolatom, you use a table to look-up the numbers.

I use [key] to implement simple controls for my program. I also use
symbolatom to accept alphanumeric input. These two uses often clash
however. If I want to enter a string that contains one of my command
letters the command is triggered. I would prefer that keystrokes are
not sent to [key] when a symbolatom is selected for input. Does
anyone agree?

Workaround: You could use a key, that is seldom used (e.g. F-keys) to disable and enable your key commands.
