why numeric control accept aef but not cds characters?

[trout00]

I place a numeric control on the front panel. It is just a simple U32. When I click on it, I can type in number, its also accept letter aefpz but when I type in cdor s, these three letters do not appear. Why the numeric control accepts some letters and rejects others?

Hi trout00

Some letters are accepted because you can enter numeric values like 13u5 which is 13.5 micro or 1.35e-5. The other letters are for the different prefixes.

Hope this helps,
