Once a keyword is marked deleted, this will go to a queue to be purged and this queue is worked down to be removed permanently. If you mistakenly deleted a group/keyword you will be prompted of the change and will have an option to Undo. If you missed this, you can still restore it within about a week. 

To restore the group/keyword:
Step 1:
Click on the gear icon at the bottom left
Step 2: Click on Archived Groups
Step 3: Select the deleted group/keyword then click Restore

This is also where you can restore your archived groups.
