The problem with this is that if the accelerators include
- keys without modifiers, such as the space bar or the
+ 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
+ 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
