It you are in Edit Mode and want to want to switch to a different entity selection (ie. vertex, edge or face) then press Ctrl + Tab and a menu will pop up on the #d View screen at you mouse pointer. You don’t need to go to the menu bar.
Remember that Shift + Tab will toggle snapping but in addition Ctrl Shift + Tab will give another popup that allows you to select what to snap to (vertex, edge, face etc.). No need to go to menu bar.
Excuse me if this has already been pointed out. I did not see it.
