Keyboard-based table navigation (Trac #1617)

[sleemanj]

If the cursor is inside a <table>, I think the following behaviors should be attached to keypress events:

• TAB: move cursor to beginning of the next sibling cell, if there are subsequent siblings in the same row
• SHIFT+TAB: move cursor to end of the previous sibling cell, if there are any previous siblings in the same row
• UP ARROW: move cursor to same position within the same-indexed cell in the previous sibling row
• DOWN ARROW: move cursor to same position within the same-indexed cell in the next sibling row

• @sleemanj commented:

Arrow navigation would make cursoring around in the text in a table cell impossible (or at best cumbersome). So closing this fixed as is with just tabs.

• @sleemanj changed resolution to fixed
• @sleemanj changed status from new to closed
