I was testing the revised searching in r12644
In "Key" view I can't seem to be able to search for stuff
like "Alt+" or "Ctrl+" .
If  I hold the "Ctrl" key and click "+"  it fills the field with "Ctrl++"
which, of course, yields no results.
Curiously in "Name" view I can type "c" "t" "r" "l" "+"
of course this yields no results in the "Name" mode now,
but if I switch to "Key" mode the search appears to
work ok,  ...
Seems to work as intended in "Tree" view.
In "key" view I see you have re-named the search box
label to "Hotkey"
Would it be better in "Name" view to rename it from "Search"
to "Name" for clarity of purpose?
