Schemas 3:
Users can attach schemas to global key shortcuts
The best example is Ctrl-C and Ctrl-V. Tn has made the
clipboard obsolete but for interoperability, Ctrl-C invokes a
schema which takes the currently selected item in the current
document and places it on the clipboard. This is possible
because all data within data appears as output points from that
data – this is how Zip archives are handled
Another example is “Email and Print” which when invoked,
emails the current document (by connecting it to
//Network/smtp/mailserver/account/Batch) and prints it (by
connecting it to //Devices/Printers/HP Laserjet)
This can get very powerful very quickly …
