I am using Gnome 3.10 on the top of Ubuntu 13.10 and the stock kazam screencaster coming with Ubuntu (1.4.3-0ubuntu1).
Kazam works properly, however the start/pause/finish shortcuts are not working at all. They're supposed to be Super+Ctrl+R, P and F respectively.
It used to work properly with Unity. Do you have any idea what's blocking them in Gnome3?
UPDATE Feb 12, 2014:
I realized that several times the shortcuts worked but not always and not consistently.
sudo apt-add-repository "deb http://ppa.launchpad.net/kazam-team/stable-series/ubuntu raring main"for the repository, instead of theppafrom the article? It seems to work in Unity using that... – Wilf Feb 11 '14 at 16:18
