I noticed in all 3 .1709 apps, that after the update and automatic startup of each app, that keyboard shortcuts were not working. I could get them to work within a document by clicking on the document in the workspace. But if I created another document they would not work in that document.
In each app, after a restart of the app, the shortcuts seem to be working normally again.
This was true for shortcuts such as Ctrl+W (close), Ctrl+Z (Undo) and Ctrl+Shift+Z (Redo), Ctrl+R (Show Ruler), and Ctrl+, (Settings).
