The shortcut key for ruler is Alt +V

Answer 2

Answer:

First, of course, you must make the ruler visible. Click on the View Menu. There should be a checkmark next to the word "Ruler." If there is, then the ruler will be visible. If there is no checkmark, then the ruler is hidden. If you want to use the keyboard shortcut to show and hide the ruler, press Alt-V and then press L.
