The screencast plugin is a major breakthrough in explaining Leo. I
estimate that creating a screencast is at least 100 times faster than
creating the corresponding slideshow. Furthermore, the effects that can
*easily* be produced far exceed anything that can be done with the
slideshow plugin.
My apologies to Tom F. for not having this ready in time for PyOhio :-) It
would have made a big difference.
Two big steps forward today:
1. It is now dead easy to put up a graphic, scaled and centered, anywhere
you like. For a cool example, see the tree:
@screencast the parts of the screen
This screencast discusses the icon box: the icons are scaled so they are
all 100 pixels high!
2. Screencasts can now simulate, fairly exactly, what happens when typing
in the minibuffer. See the tree:
@screencast minibuffer
This screencast shows tab completion in action. It's quite nifty.
To run any @screencast node, just select it and hit Alt-9 in test.leo.
Screencasts are the perfect tools for creating videos about Leo. They
easily stand all by themselves, but if a narrative is wanted one does not
need to do anything except hit the right arrow button and talk. No need to
do any real typing. No mistakes. Folks, this is the most exciting work I
have done in a long time. A little bit of effort creating "tools" in the
screencast plugin goes a long, long way.
Next up: a screencast about Leo's find/change commands.

P.S. The yellow background in the caption area comes from this part of the
stylesheet in the @data qt-gui-plugin-style-sheet node in leoSettings.leo::
QPlainTextEdit#screencastcaption {
background-color: yellow;
}
As usual, you can change this to anything you want in your
myLeoSettings.leo.
