Command Shift K Not Working
 

Does anyone know why out of the blue "command Shift K" is not working? I am using Pro Tools 11 on an iMac running Yosemite. Thanks!

You might check the clip list.
If the clips, you want to export, are not shown there, due to a clip list search that has not been cancelled or because the type of clip is not enabled in the clip list menu (show - audio, midi, ....), then those clips, who are only selected in the edit window, cannot be exported.
Cmd Shift K, that shortcut "belongs" to the clip list, not the edit window.

Does running the command from the clip list mini-menu work? If not, then it's probably something like what Joachim is suggesting. If it does work from the mini-menu, then it's probably an issue with a keyboard shortcut assigned in system prefs stealing it.
