Personally I think all the typing takes away from the roll-play so let us just eliminate it and the problem is solved. More seriously though, Why should there not be textual short cuts, possibly player editable, for common descriptive elements? Sure you can make a shortcut for /say or /shout or whatever but the number of shortcuts is limited and it would be better to have text variables that could be interpolated in-line. You find it awkward? don't use it.
As for the example it would likely become "bilbous blah blah blah. bilbous smiles."
The less typing I have to do in game the better I like it. Typing is an OOC action and hinders immersion. If I wasn't so lazy, I might try running the game through a speech recognition engine and do away with typing altogether.
