The keys Ctrl/PgDown and Ctrl/PgUp ( next and previous navigator node) do not work in the editor when editing plsql package. When you click any of them, the cursor jumps to the beginning of the text.
When I edit the procedure, the keys work correctly and go through the internal routines.
This bug first appeared in 14.1 and still doesn't work as expected.
Is it possible to fix it with the settings?
