Hello!
I’d ask something very special
I need to markup my text so it would correspond the so called ‘Stephanus pagination’. It should go like this: 113a1; 113a5; 113a10; 113b1; 113b5; 113b10; ……. 113e5; 113e10; 114a1; ……….

So the field should work as a complex 'counter', consisting of three parts. The first ‘counter’ should be incremental. The two other ones should be cycled (a …… e & 1……. 10).
I’d like to insert such fields using some keyboard shortcut. And they should look like this:
The initial values for all these ‘counters’ should be definable. I.e. for example, I should be able to begin with [17d5].

Is this possible at all?

Any help would be most appreciated!
