Link category selection from keyboard

[kim]

When adding a link (wp-admin/link-add.php) the list of categories is sorted by ID and has the ID prepended to the category name. To select a category using the keyboard, one would need to remember the numeric ID of the category.

I think usability would increase if the list was sorted by category name, so that the category can be selected by typing the first letter of the category (repeating the keypress will cycle down entries beginning with the same letter).

Attached patch implements this change.

To provide a more uniform UI to match with the suggested change, I modified the list of link categories (wp-admin/link-categories.php) to also sort by category name rather than ID by default. However, at times it can be useful to be able to locate a category easily by its ID number, so I also added sort order selection through links in the table heading cells (by ID and by name).

Second attached patch implements this.

Great idea. Invalid now, though with new interface.
