I'm guessing that the example review will be opened as a separate issue?

Fixed in commit 200afa4.

Yes. But, I will be postponing that review and discussion off to the next APG release and marking the current implementation as a proposed implementation that does not yet have task force consensus.

1. In the context of a feed, the web page code is responsible for:

In this item, "web page code" seems ambiguous, like we're shifting blame to the code rather than the author. I'd prefer "web page author," which does appear elsewhere in the document, including the final paragraph of the feed description.

No other issues.

Hi @mcking65. Thank you so much for the Feed Pattern, it's lovely.
I have a question about adding the Ctrl- modifer to the Home and End keys, e.g., in your document here.

I surveyed the other APG patterns (listed after this paragraph) and found considerable use of Navigation keys. In many cases Home and End are left unmodified. Do you have a strong rationale for using modifiers in the Feed Example, or would you advise leeway and not object to unmodified use? Many thanks for your guidance.

@mendeza asks:

The recommendations for keyboard commands intend to reflect similar conventions. Typically, unmodified home/end stay within a narrowly scoped context where as when modified by control, they make a larger change within the context. For example:

• home in a grid moves to start of current row while ctrl+home moves to start of first row
• Home in a text field or doc moves to start of current line while ctrl+home moves to start of first line

In the context of feed, ctrl+home and ctrl+end are more akin to moving to top of doc and bottom of doc than start of line and end of line. That leaves options for home and end to be used within a smaller context, e.g., start of article and end of article, which are commands we did not define. As a new pattern with no precedent in native Windows, macOS, or Linux, the feed pattern is still somewhat a solution in incubation. That is part of the rationale for keeping this issue open for feedback and questions.
