Hi there.
A character set is what you need.
Note:
A character set is not just for character animation but for any set of attributes you want to key all at one time.

1. Select your objects channels t,r,scale etc.
2. Create character set.
3. Then in the channel box with your shader selected, highlight the channel in your your case incandescence. Then go to menu> character>Add to character set.

Make sure it is active down in the range slider every time you key all in that set gets keyed and moved all at the same time.
