I am following instruction how to use IRC OTC. Unfortunately a simple steps C and D is not possible. The button/tab certificate import is not greyed out and not selectable. So I don't have much of a chance in continuing.

keys start with: -----BEGIN PGP PUBLIC KEY BLOCK-----
keys end with: -----END PGP PUBLIC KEY BLOCK-----
b) To get these keys into kleopatra, select the entire key (including the begin and end line), and copy them to your clipboard (crtl+c or edit=>copy)
c) Right click your red kleopatra icon in your task bar
d) select Clipboard and then certificate import
