Not sure why that's not working for you. Let me download it from the chrome store and see. it's working for me on chrome osx 64bit same version of chrome.
Perhaps try restarting chrome and if that doesn't work you can try uninstalling the extension and reinstalling it. I just got the extension from the chrome store and command-shift-E worked fine. there is also the possibility that you have command-shift-e shadowed by another command(system wide shortcut or another extension). try going to chrome:extensions and going to the very bottom and selecting "keyboard shortcuts" and changing the one labeled "Toggle or activate a Tabist tab" the Tabist entry.
feel free to email me at the email in my profile if that doesn't work or if you figured out what the issue was.
I think the problem was that I had Tabist installed before, and so the suggested keybind didn't take effect when I upgraded to a new version. Not a big deal with only a few users.
EDIT: On second thought, I have Tampermonkey installed, which apparently defaults to Command-Shift-E: http://i.imgur.com/DAEvgNB.png I think that was shadowing it.
Yeah, this extension rocks! I'm going to use this forever.
The only other feedback I have is that when you open Tabist and click on a tab, it'd be nice if you automatically close the tabist tab (and if possible to re-focus the previously active tab, which isn't necessarily the rightmost tab). Otherwise you end up with multiple windows with Tabist in focus.
This is fantastic though. I've been telling my friends about Tabist and everyone's saying how useful it is.
