4) Please <b>DO</b> use the bugtracker at http://tracker.ardour.org/ to report issues\n\
making sure to note the product version number as 5.0-pre.\n\
5) Please <b>DO</b> use the ardour-users mailing list to discuss ideas and pass on comments.\n\
6) Please <b>DO</b> join us on IRC for real time discussions about %1 %2. You\n\

key events. The normal sequence is:
a) event is delivered to a GtkWindow
b) accelerators/mnemonics are activated
c) if (b) didn't handle the event, propagate to
the focus widget and/or focus chain
The problem with this is that if the accelerators include
keys without modifiers, such as the space bar or the
letter "e", then pressing the key while typing into
a text entry widget results in the accelerator being
activated, instead of the desired letter appearing
in the text entry.
There is no good way of fixing this, but this
represents a compromise. The idea is that
key events involving modifiers (not Shift)
get routed into the activation pathway first, then
get propagated to the focus widget if necessary.
If the key event doesn't involve modifiers,
we deliver to the focus widget first, thus allowing
it to get "normal text" without interference
from acceleration.
Of course, this can also be problematic: if there
is a widget with focus, then it will swallow
all "normal text" accelerators.
