Inserting a specific keybinding might (?) be best in a bundle defaults? @techee may have an opinion on the MacOS part
Is there anything like a global keybindings file that could be placed to a bundle and to which the settings would fall back? Maybe I miss something but the only `keybindings.conf` I see in the code is inside configdir and this one has to be created by Geany.
Note that unlike Windows there is no real installer executable that could possibly create the file - the dmg file is a disk image (something like iso) which gets mounted when double-clicked which contains the app bundle (simple directory with an app extension) which the user drags-and-drops to the destination Applications directory where other apps live.
I think this leaves the `#ifdef` as the only solution.
