ARIA Practices advice for left/right keys (e.g. horizontal slider) does not take into account right-to-left (RTL) languages like Arabic and Hebrew.

As part of the AOM explainer, I tried to account for that slider pattern in this table. The authoring practices pattern won't be quite so complicated, but it should be updated to invert the left/right keys if the computed value of dir is rtl.

For horizontal sliders (as determined by the computed value of aria-orientation):

• LTR or indeterminate: Increment with Up or Right, decrement with Down or Left.)
• RTL: Increment with Up or Left, decrement with Down or Right.)
