Description of the bug
You have to hit enter to search on the Add Volume page, and this doesn't work with the numpad.

To Reproduce

1. Go to Volumes > Add Volume
2. Type in a comic name
3. Hit enter on the numpad - nothing happens
4. Hit enter using the main enter key - it searches as expected

Expected behaviour
The numpad enter key should work the same as the regular enter key.
