UltraEdit: keyboard-only way to switch focus in split view?

"Use F6 to switch focus between the two panes of text in split mode.

I found the solution by going to menu Advanced/Configuration/Key Mapping and pressed button ""Show key mapping in editor"" to get the list of keyboard shortcuts into an editor window. I then searched for ""focus"" and this one seemed to fit the bill (and it did):

F6 FocusNextPane Switch to next window pane

(Note that the cursor in a pane may not be visible and thus there isn't any indication whatsoever which pane has focus (at least not in older versions of UltraEdit). The workaround is to do some non-editing action, like pressing the right arrow, →. This will bring the blinking cursor into view and thus indicate which pane has focus.)"
