In many software programs that I use you can click at a place showing
in one pane, then shift-click at a location showing in another pane.
Everything in-between is then selected. This applies in particular
with spreadsheets.


This does *not* work in TeXshop's panes; at least not in version 2.14.
It seems that the panes record their clicks separately.

e.g.
    * Click in top pane sets an insertion point.
    * Shift-click in lower pane selects from top of source
      down to the clicked point.
    * Shift-click in top pane selects between this point
      and the previous insertion point.

That is a nice idea, for representing a selection that does not
fit entirely within the scrolling window.

Shift click lets you either extend or reduce an existing selection.

In Mail this only lets you adjust from the bottom end.
In TeXshop, it seems to work at either end.

In many Mac programs, you don't have to wait.

Even in TeXshop, it is rather silly to select-drag-scroll;
that is indeed time-consuming.

Better is to click, scroll using the scroll-bar, then shift-click.

Hope this helps,
