I'd like to be able to read all my news by keyboard commands alone, like I could with the original Google Reader. A lot of things are implemented, but many are not.

For instance, I cannot navigate between feeds like I could on Google Reader with Shift-p/n commands.

Google Reader offered the following commands:

Navigation
j/k: next/previous item
space: next item or page
<Shift> + space: previous item or page
n/p: item scan down/up (list only)
<Shift> + n/p: next/previous subscription
<Shift> + x: expand folder
<Shift> + o: open subscription or folder
Application
r: refresh
f: toggle full screen mode
u: hides/unhides the left hand side module
1: switch to expanded view
2: switch to list view
/: move cursor to search box
a: add a subscription
=: increase magnification
-: decrease magnification
Jumping
g then h: go home
g then a: go to all items
g then s: go to starred items
g then u: open subscription selector
g then t: open tag selector
g then <Shift> + t: go to trends page
g then d: go to discovery page
g then e: go to explore
g then p: go to popular items
Acting on items
s: star item
t: tag item
e: email item
<Shift> + s: share item
v: view original
o/enter: expand/collapse item (list only)
m: mark item as read/unread
<Shift> + a: mark all as read
<Shift> + t: open “send to” menu
