Re: [gtk-osx-users] Is there a way to override default key bindings?

do You remember when this was fixed? I tried latest moduleset, indeed, key bindings seems to be OK, but I have got number of other issues (I will write separate message on this). So, probably, for me it would be better to patch old good 3.6.4...

No. I wrote on a Gramps bug in early July that I'd found it and backported it to 3.8, but the only commit that fits the date is
and that seems to be in the wrong place.

I think you'll have to re-do the bisect. Sorry.

But this way I am having both ctrl+v and cmd+v doing the same thing - pasting text, for example. And having to handle this for each widget separately is not something that one would be wanting to do.

It was a Gtk bug, since fixed. Rebuilding with the latest modulesets will get you your command-key accelerators and bindings back... with one caveat: Don't set use_quartz_accelerators to TRUE, because then the menu accelerators grab the key binding before gtk can see it, and it gets sent to whatever window has menu focus instead of the one that has keyboard focus.
