search in key does not actually highlight as it goes

[themusicgod1]

1) open clipboard
2) type something like "blah"
3) hit 'encrypt' button

a (unwieldly large) list of public keys shows up, with no 'help' in finding
a) any keys that you have ever successfully used.
b) any way to sort the keys based on use
c) any particular key

4) hit Control-F

this brings up a search window, great that will help me find the person I'm trying to write to on this utterly massive list.
I notice, though as I type

what currently happens:
nothing

what should happen:
do something like Filter the public keys to only match the words you type, so if I type "jeff"
only keys matching "jeff" should show up.
