you're not expected to edit the files directly.

please go to keyclone/setup/keymap-editor ... hit 'load' ... select region1.kcl (or whatever file you are using)... and tweak that. select a line, change the key, or hit the DEL key to delete an entry from the list. remember to save the file.

if you change or add a hotstring, remember to add it to all the other keymaps you are using
