I've read many places where this is asked:
"I used to "xxx" in v3 but I can't find how to do it in V4"
Maybe we should start a thread like so:
Task: Scroll to next bible chapter
V3
use space bar
V4
ALT + Up or down arrow
Task: resize windows
V3: drag by edges of window to resize
V4; Hold tab area and drag until a blue representation appears/ release.
Anyway...you get the idea...that way all this transfer of knowledge won't get lost.
