Summary of Issue: Technique has poor and undocumented browser support
Comment (Including rationale for any proposed change):
The techniques described in FLASH17 regarding keyboard access to a Flash object, and the working example, only work in Firefox and IE for Windows. They don't work in Chrome (Win/Mac) or either Firefox or Safari for Mac.

The technique makes no mention of these limitations, which seem unreasonable (doesn't seem to work in any webkit browsers at all).

Proposed Change:
Short term: Update the technique to reflect the current level of browser support.

Long term: Modify the techniques to increase the supported set of browsers (especially webkit).
