If you want to see format control characters as visible symbols, which is what your example is about, then there does not seem to be any direct way. But if you click on the “¶” button (in the Start pane, Paragraph group in new versions of Word), Word adds symbols at ends of visible lines to indicate presence of such controls, e.g.
Hi,·¶
How·are·you?·¶
Here “¶” indicates the presence of CR (U+000D CARRIAGE RETURN, “\r”), whereas a symbol resembling “⤶” would indicate LF (U+000A LINE FEED, “\n”), which indicates a forced line break without paragraph break in Word. And “·” indicates a normal space (U+0020 SPACE), whereas “°” would indicate a no-break space (U+00A0 NO-BREAK SPACE).
For visible characters, the AltX method described by @JasonPlutext works well. You don’t even need to select the character. You can just click between it and the next character, to place the cursor there, and then press AltX.
