Keyboard-driven method for reordering rows

[jrchamp]

This idea was brought up before:

          It would also be massively useful when trying to provide a keyboard-driven alternative method for reordering rows, for use by the vision-impaired or others with special needs.

We want to provide row reordering functionality for our users, but if it doesn't work via the keyboard, we wouldn't be able to provide an equitable experience for our users. It would also open us up to legal concerns.

As far as implementation:

• The draggable selector needs to be focusable
• A keyboard shortcut that is already popular for manual sorting (for example, Google Tasks seems to use Ctrl-UpArrow and Ctrl-DownArrow)
• Optional: For the keyboard, the position calculations shouldn't need to use X/Y coordinates. Thus, it may be good to segment the existing code such that the "where did the mouse/drag start/end" code that calculates the old and new positions is separate from the "change row position" code.

Thank you for considering this request! ❤️

Hi,

Thanks for opening the request. Yes, I think this is something that should be done. I don't know when I'll be able to get to it though to be honest. Hopefully it won't be too far away, but I'm working on other aspects of DataTables at the moment.
