If you write documents in HTML format, it may be useful to symbolize key keyboard, for example when the user is prompted to enter a certain combination of keys.

Here is a simple way to do HTML:

Code:
 <style type="text/css"> <! - body (font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10pt; background-color: white; span.touche) (margin-right : 1px; padding-left: 2px; padding-right: 2px; border: 1px solid # 6f6f6f; background-color: # cfcfcf; border-radius: 0.2em; font-weight: bold;-moz-border-radius: 0.2 em;) -> </ style> <span class="touche"> Type A </ span> <span class="touche"> ↵ Entry </ span>
Here is a variant with a small effect of relief:

Code:
 <style type="text/css"> <! - body (font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10pt; background-color: white; span.touche) (margin-right : 1px; padding-left: 2px; padding-right: 2px; background-color: # dadada; border-radius: 0.2em;-moz-border-radius: 0.2em; font-weight: bold; border-style: outset ; Border-width: 2px;) -> </ style> <span class="touche"> Type A </ span> <span class="touche"> ↵ Entry </ span>
