Win7 64bit | 2.62.3 (45364)
Problem 1: When trying to Add shortcut menu for any one of the three items in "Mesh Select Mode" menu (Ctrl Tab), it will set it to the other two. It has to be configged through the User Preference -> Input -> Window, manually.
Problem 2: Even the three items can be assigned to separate keys, however, the Vertex and Face keep displaying as the same, in the Ctrl Tab menu.
For more details, please see below link for what I've described (my 3rd post under the thread):
FYI, Thanks a lot.
