It would be handy if the focus by default uses no range (range of 0). Also it would be useful if it was possible just to create values below or above the referenced values. A syntax change could be useful.
Good:
@ x |min:max| in |min:max| step N
That is:
'@' identifier range ['in' range] ['step' number]
OK.

You seem to have CSS turned off. Please don't fill out this field.
The definition
|expression:expression| in |min:max| step N
would be a generally good definition for all ranges. In particular if variables are used, the '@' thing could be dumped!
|x-1:x+3| in |0:255| step 2
