There have been some changes to key bindings for PC with the 1.2 patch for Skyrim.
.
Keys like "R" and "T" for take all, store and recharge no longer function and the alternatives are to standard bound key functions which is a great improvement because now, for the first time, it is possible to unlock shouts on some PCs (such as my one).
.
Anyway, just in case anyone is still looking for one of the new key bindings I thought I'd share what I've stumbled over while bumbling around in the game environs:
.
Action................................Bound Key by Function
Shout Activation.................Draw/Sheath Weapon key [in shout menu]
Take All..............................Draw/Sheath Weapon key [in container menu]
Store highlit Item................Draw/Sheath Weapon key [in personal inventory menu]
Rotate Lock........................Strafe Left, Strafe Right, Move Forward keys [in lockpicking mode]
Set Favourite......................Change view/Perspective (1st/3rd person) key [in personal inventory menu]
Charge Weapon.................Wait key [in personal inventory menu]
Exit Menu...........................Menu key, {Esc} key
.
While the keybinding tips in the menu system are yet to be updated, it might be handy to have information like this somewhere where people are likely to look for it...
