Before, I love Evernote, I used to Evernote helper with short cut - ⌘ + ⌥ + space.

but, I can't use this anymore.

I just swept up all my data, re-install mavericks.

just changed Special Characters short cut to ⌘ + ⌥ + T. (it was ⌘ + ⌥ + space)

BUT, I still can't use this shortcut for Evernote helper.

Evernote only says -

The key combination ⌘ + ⌥ + space can't be used! The key combination "command + Control + Space" can't be used because it's already used by a system-wide keyboard shortcut. (If you really want to use this key combination, most shortcuts can be changed in the Keyboard & Mouse Panel in System Preferences)

-

but I already changed Special characters' shortcut. Help me....
