In MI 6, Shift+Ctrl+Arrow Key does the same thing as Ctrl+Alt+Arrow Key, which is to move a document around the tree. It would better if Shift+Ctrl+Arrow Key could be used to select a word or line in the text pane, which is the function it is used for in MS Word (and I believe in prior versions of MI).
I didn't see a way in Keyboard Shortcuts to manually reassign Shift+Ctrl+Arrow Key to that function.
Thanks.
[fixed in 6.03] MI 6 Shift+Ctrl+Arrow Key
It will be fixed. Thanks for noticing!
