{replace with} softkey usable for parametres values (e.g: replace shutter thrust D value with B)

Wouldn't this just be the same as, in your example, Shutter Thrust D [Copy To] Shutter Thrust B?

no, this should be: shutter D takes B value and shutterB take D value. If i just copy shutter D to B, i loose B value

So you're looking more for a swap function

exactly,  i used replace with because i thought to remember eos already used for some points replace with as a swap function. probably my mistake here.

then i ´ll post a new feature request, with right words this time, thanks for correctibg me here
