How can I add a longpress with a base Unicode character + a diacritic mark

I would like to have longpress on my touch keyboard that generates output that doesn’t have a single Unicode character, e.g., Y with ogonek. I cannot figure out how to do this with KM Developer 14.0.

Hi @CraigC,

In Keyman 14, you can do this by defining a rule for the longpress key. Give it a key identifier, e.g. T_Y_OGONEK and then add a rule in the keyboard layout source (in the main group):

+ [T_Y_OGONEK] > 'y' U+0328

In Keyman 15, we will have support for extended Unicode key identifiers, e.g. U_0079_0328 which will do the same thing without needing a rule.
