Copy and paste Dekink

Dear Glyphs,
I want to copy and paste the RMX dekink function in my Custom parameters before exporting the font. Copy is clear but how to paste? I can only choose from the list.

if you get it from the filter directly, just click into the custom parameter area and paste.

Ok, Thanks Georg. It’s clear.

The best idea is to select all masters and then add the parameter. That will add the same parameter to all (selected) masters.

Good. Thank you.
