mouser,
Thanks for implementing Ctrl-F for the filter

Unfortunately... I find a glitch with using the filter (not sure it's a bug). Suppose you type something into the filter box. The text appears in red. Further suppose you have several hits. If you go straight to one of those hits, with the text still in red, and click it, CHS reverts to the
last thing you typed into the filter, if there was one, with the text in black. If there wasn't anything in the filter before, it might be doing something random, but I haven't checked that properly.
On the other hand, if you go to the filter, enter your text, see it presented in red
and type Enter after it, the text turns black and everything proceeds as expected; you've "locked" the text in the filter and can choose from the list of hits. In other words, the final Enter is obligatory.
I don't say that behaviour is exactly wrong, but I wasn't expecting it. Does it need to be trapped?
