- rename prop-key-handler.nas to prop_key_handler.nas (the hyphens were
intentional, exactly to *make* using it as namespace less inviting,
but times change ...)
- add property browser binding to the '/'-key for when the property key handler
is turned off (/sim/input/property-key-handler=0). If it's on, use /: or
/<property>: to open the browser.
- run keyboard event listener only when property key handler is active
I hope that the '/' key can keep this binding even after a keyboard review.
The '/' is just the most natural key for dealing with properties, and it's
far less prominent on non-US-keyboards (e.g. Shift-7 on German keyboards),
so it's not really very well suited for important aircraft functions, anyway.
But I don't insist. :-)
- allow turning on/off extra widgets for developers (HUD dialog: colors,
rendering dialog: visualization of shadow edges), and to turn on/off new
- property key handler ('/'-key)
Both features are off by default, and their state is saved to autosave.xml.
