Tom,

That's why we're doing Best Practices, don't we?

Think of FireFox. Having 10 Tabs open and arrow keying with additional
focusing of the closing cross icon will result in a keyhitcount of 18 to
navigate the tabs instead of 9.

And don't tell me Firefox isn't a good example :) (just kidding)

So currently we solve the issue for Tabs in our Web Dynpro frameworks
with memorizing special keys in the tab tooltip in cases where it does
make sense.

I also think the icon attached to the tab or in the tab order may also
be helpful. We need to consider cognitive load when talking about
keyboard shortcuts. Too many web and software apps to track/memorize.

Jon,

better to have a standardized hotkey for closing tab. As a concept we
tend to keep tab chains short.

Regards
Stefan

Why can't the close icon be in tab order and the icon can also be part
of the label for the tab.
