Visual symbols for Carriage-Return and Line-Feed
For exactly this purpose, there are Unicode control pictures for CR and LF
Post /destination?param=value HTTP/1.1 ␍␊
Accept: text/html, application/xhtml+xml, */* ␍␊
In the above example, "␍" and "␊" is each a single character (not a pair of characters).
In Word you can use reverse highlighting etc to further highlight these characters.
The above are
- U+240A ␊ Symbol for Line Feed
- U+240D ␍ Symbol for Carriage Return
Other (arguably more ambiguous) Unicode symbols that are in Arial Unicode MS and which might be used include
- U+21b2 ↲ Downwards Arrow With Tip Leftwards
- U+21a9 ↩ Leftwards Arrow With Hook
- U+2199 ↙ South West Arrow

- U+25C4 ◄ Black Left-Pointing Triangle
- U+25BC ▼ Black Down-Pointing Triangle
Entering Unicode characters in Microsoft Word.
There seem to be several methods:
- type the hexadecimal code and press Alt+X
- type the hexadecimal code and press Alt+C (see comment below)
- type Alt+0 decimal unicode value (need for 0 depends on language)
- type Alt+x hexadecimal unicode value (may need registry tweak†)
- press Alt+Shift to invoke IME, enter hex code (install CN/TW IME first)
- start, run, "charmap", locate character, select, copy, alt-tab, paste
- Cut & Paste from another source (web-page, PDF, etc)
- Create your own shortcut using Word's insert, symbol dialog.
Note: Some of the above may only apply to specific versions of Microsoft Word or may depend on system settings (e.g. locale related settings).

Remembering Hexadecimal or decimal codes is difficult. For frequently used characters there are easier to remember shortcuts‡ in Word.
