 - The help fits short terminals: no banner, two columns when one is too tall, and it scrolls
   only when neither fits. Shift+drag text selection is listed under NODES.
+- `m` turns the mouse off and on, so a plain drag selects text; the zoomed pane has no side
+  borders, so a selection there is just the log text.

-The mouse is on, so to select text hold Shift while dragging (Option in iTerm2).
