Compose key won't enable

Question

Right now, I'm trying to enable my compose key to type characters with accents. It wont enable.

I'm in the system settings panel, and all it says is:

Compose key............................................................ Disabled

However, when I click on one that does have something currently in it, it gives me the option to create a new one:

Switch to previous source ................................. New accelerator

It never shows the option to define a "New Accelerator" for the compose key, rather it just stays in the 'disabled' mode.

Please help!

Running: Ubuntu 13.10

Computer: Acer Aspire 5250

All updates are enabled, except for preliminary.

Answer 1

For the compose key, you have to select a key from the drop down list displayed while clicking the disabled option.
