One of my favorite features in the old version of Evernote was doing a CTRL+; for adding a date time stamp with two keystrokes.
I didn't see the logic in breaking that up into 2 sets of 3 keystrokes each and by the way, it looks like CTRL+SHIFT+D for the Time stamp no longer works at least in the version I'm using, 10.61.
Also, are you planning to bring back ctrl+; to add a date time stamp or can I customize that keystroke in Evernote?
