In the new LR video 08i_Library_Pt1, Mr. Reichmann and Mr. Schewe discuss keyboard shortcuts for navigating the Library module of LR 4. They appear to be puzzled as to why "E" was chosen for the shortcut :go to the loupe:. Of course, "L" is already assigned to :lights out:. One of guidelines for assigning shortcut keys is, if the first letter can't be used, consider the last letter. Thus "E" from "loupE". The mnemonic to help the user to remember it is "E" is a "loopy" shortcut for loupe.
