Further info.

1) Forget about the keyboard focus problem: it happens even if "Continuous" is
not selected, though a third ESC always gives back control to the keyboard. So
I guess this is a global KDE "feature" ;-).
2) PgUp works fine irrespective of "Continuous" and/or "Trim margins" modes. 
3) PgDown:
- in normal mode (no continuous, no trim): scrolls correctly one page though
often jerkily (slow page load/refresh?);
- in "Continuous" + "Trim margins" mode: misses a scroll every 2-5 hits, enough
to be irritating. This happens irrespective of the memory usage setting.

Maybe the weird PgDown behaviour depends on bad forward page caching?
