Office 2016 FORCES us to now go to a Drop-Down Menu OFTEN ... when before the action could be done with a keystroke:

Examples:
1) Command W ... to close a file ... now forces you to move your mouse cursor up to the blue word SAVE ... rather than simply hitting the letter "S" (which is right below the letter "W"). We should be able to hit the letter "D" for "DON'T SAVE" as well

2) BORDERS: I often use the "option+command +arrows" to provide borders. SOMETIMES IT WORKS ... Other times it does NOT WORK ... and I have to go to the "Command 1" feature and select the BORDER option before I can get the border I want

3) COMMENTS: the "rollover" feature does not always work (EVEN THOUGH IT IS SELECTED IN PREFERENCES) ... and we are forced to right click ... select "show comment" and when finished we must go back and select "hide comment". FIXING THE ROLLOVER FEATURE FOR COMMENTS IS A MUST.

4) etc. etc. etc.
