Very interesting, haven't noticed it.

When you execute ipdf from shell, ipdf will use channel 2 but CLI will wait on channel 14 (maybe vice versa). That's why UP button won't be functional in this case.

hmmm...
Neither ipdf or FBreader listen to UP key when running from the CLI, so it must depends on how the apps are started.
Anyway, first question remains... who is listening on the other side of the IPC mechanism? how keyboard is shown?
