How to use the cursel feature (as of 00-08-04)
"Cursel" means "cursor selection." There is now a mode where you can choose
between different cursors for a view. Here are the instructions as to how.
In normal mode:
Alt-C -- switches to cursel mode. I like to reconfigure this to spacebar --
much faster. Note that the view's background now shows the color of
its current cursor -- useful when there are multiple cursors on the
same cell.
Esc -- now re-attaches the standard cursors to the views before it moves
them to the home cell. When you're lost, hit Esc.
In cursel mode:
Left/Right arrow (or sf or jl): choose between cursors on the system list.
Up/Down arrow (or ec or i,): choose between cursors on the same cell as the
current cursor.
Tab or Spacebar or Esc: Select this cursor, quit cursel mode.
To get four additional cursors:
With the left view, go to "CreateCursors" on the Action list. Hit Enter.
Note that you can apply this multiple times, but it'll give you multiple
cursors of the same color.
To bind the two views together:
Go into cursel mode. Hit Left, Right, s, f, j, or l until both views have the
same background (and thus, cursor) color. Quit cursel mode.
To bind a view to a "magic cursor:"
Go to the first entry on the FlobRaster list. Make sure at least one of your
views is shows this raster. Go into cursel mode. Hit Up/Down (or e/c if you
use the left view) until the background of your view gets white: this means you
have attached the view to a cursor without an associated color. Raster cursors
don't have associated colors (at the time I'm writing this). Now quit cursel
mode. Move the cursor up and down and watch what happens. (Easiest way to get
back to normal from here is to hit Esc.)
To show very clearly how the cursing system in ZZ works:
Create the four additional cursors (see above). Edit the dimension list so that
d.cursor is on it. Cursel the golden cursor, go to the FlobRaster cell on the
system list, and go to the rightmost cell. Now cursel the violet cursor and go
to the FlobRaster cell. Make sure at least one of your views is set to the
standard vanishing raster (whose cell is between your two cursors now). Rotate
the view so that d.1 is on the X- and d.cursor on the Y-axis. Now play around
with the violet and the golden cursor, and show how the connections on d.cursor
change.
