I can fix this but I don't know what you're trying to achieve by nesting a < code > block inside a < viewer>, please let me know.

JohanB wrote:[esc] would be ideal but you've already used that for pause,
seeing as there are many other keys also assigned to pause, I'd still like to campaign for [esc] = close.

1. [esc] closes the standalone LifeViewer but pauses playback on the inline LifeViewers
2. [esc] closes the standalone LifeViewer and does nothing on the inline LifeViewers
3. we pick a different shortcut key

JohanB wrote:2. Is it not possible to have the viewer grab the keyboard focus when it starts?

• If I press [space] did I want to toggle playback on the LifeViewer or have the browser page down?
• If there are multiple inline LifeViewers on a page which do I want to interact with?
