certain functions not working

[bootos]

surfing keys does not seem to be working
for certain functions.

can you help me fix it? thank you.

1. this is suppose to open bookmark omnibar
   enter the letter b
   then press enter key
   and go to first url in current tab
   but it does not do that
   instead it opens up bookmark omnibar
   that's it
   how do i make it work ?
   it seems feedkeys not working.
   mapkey(',/', '#8Open a nextbookmark', function() {
   api.Front.openOmnibar(({type: "Bookmarks" }));
   Normal.feedkeys('pbp');
   });

2. this does nothing.
   it seems to be feedkeys again.
   it suppose do same as above.

map(',;', ':feedkeys pbp', 0, "#3Go bkmk ");

3. this does nothing.
   it should delete the bookmark.

   even when i comment out feedkeys
   and go to a bookmarked webpage in a tab
   and press this ,it does not remove the
   bookmark.

mapkey(',r', '#14Remove bookmark for current page', function() {
///alert(window.location);
Front.openOmnibar(({type: "Bookmarks"}));
Normal.feedkeys("pbp");
RUNTIME('removeBookmark');
}
);

5. this not work.
   but if i enter the fontsize code into
   tampermonkey, it works.
   why does it not work in surfingkeys?
   any solution would be appreciated.
   i have been trying to solve all these 5 problems this last 2 weeks.
   thank a lots in advance.

mapkey(',9', 'fontsize 42', function(){
window.document.body.style.fontSize="42px";
});
