That had passed me by. The new keys are handy, especially the comma. More things to put in the Guide / wiki!
Is that the famous 'backtick'? I have trouble with some characters on my Brazilian keyboard: for instance the tilde ã for /home won't appear without a letter under it, though in some apps it does (including Ratpoison's terminal emulator; I don't understand the behaviour in a true terminal at all) by typing twice, as normal. My theory is the backtick is what in Portuguese is a grave accent à but without a letter underneath. Same difficulty.
I've booted into the beta to compare with the original version of Vimprobable, and f definitely seems more responsive than in the new version. I don't know if that's because it works before the page has finished loading, or perhaps because it doesn't hang if called early.
Some pages take a while before you see any content at all, but as soon as you do, f works. Also nothing whatsoever appears at bottom left when you press f, such as `.
The yellow highlighting is only applied to the parts of the page you can see, so link 1 is always at the top of the screen wherever you are on the page. If you scroll up or down, there's no yellow. Presumably this is the same in the new version.
