Hi,
since "mmodes.pdf" isn’t part of the distribution anymore, where are
modes documented, and is there a current list of system modes?
(Yes, I know https://www.pragma-ade.nl/general/manuals/mmodes.pdf and
https://wiki.contextgarden.net/Input_and_compilation/
Conditional_processing_with_Modes)
Are there modes that I can check for a left/right page, or is
\ifodd\pageno the better way?
Modes won't help you in this case because the act like a conditional
check at the place they occur.
When you need an odd even check in header or footer texts you can use
\doifelseoddpage{...}{...}, in the page body the command can fail and
you need \doifelserightpage{...}{...} but you have place
\signalrightpage before it because ConTeXt has to use multipass data.
