# SPACEHANDLER.VIEW3D.EVENT
#
# 2007 Carsten Wartmann
#
# The space handler scripts ShowKeys and DrawKeys are showing
# the actual pressed keys in the 3D View.
#
# This is usefull for presentations or video tutorials where the
# key-combinations
# will give some hints whats going on beside the narration.
#
# To use activate the handlers in the View->Space Handler Scripts memu
# The display will be for the 3DView only and need to activated for
# every
# 3DView you like to see the keypresses.


"""
Problems/Todo

* Tab and Space not showing
* some functions CTRL-Q, CTRL-W etc. not showing
* while in Transformation (GSR) the script gets no events
* B-B combination (Circle Select) not handled, maybe do the same for A-A?
