Editing Template:Documentation (section)

== Usage ==
The template takes one mandatory parameter, the content to be marked up.  If this content contains "=" (an equals sign), the parameter {{em|must}} be explicitly named {{para|1}}, or the template will fail. (This is a limitation of the MediaWiki software, not the template.) It is always safer to use {{para|1}} syntax. It may be used as a container for {[tlx|var}}, {{tlx|varserif}} or {{tag|var}} when the example keyboard input contains or consists entirely of a variable. It may also be used with (but not inside) {{tlx|code}}, or with {{tag|code}} (it generally should not be used inside the latter, as input is not a part of source code, but something that interacts with it; however, this style can be used to illustrate computer display of mixed type, as illustrated below).

There is an optional parameter {{para|spacing=no}} (or {{para|spacing=n}} or any other value), to get rid of the slight letter spacing, which can look awkward on long passages of input.

Examples:
* {{tnull|kbd|71077345}}: "Entering {{kbd|71077345}} on a calculator and turning it upside down appears to spell ''[[Royal Dutch Shell|ShellOil]]''."
* {{tnull|kbd|1{{=}}ssh <nowiki>{{var|hostname}}</nowiki>}} with {{tnull|samp|%}}: "At the {{samp|%}} prompt, the user must enter {{kbd|1=ssh {{var|hostname}}}}."
* {{tnull|kbd|1{{=}}ssh <nowiki>{{var|hostname}}</nowiki>}} with {{tnull|samp|%}} and {{tnull|key press|Enter}}: "At the {{samp|%}} prompt, the user must input {{kbd|1=ssh {{var|hostname}}}}{{key press|Enter}}."
* Inside {{tag|code}}: "The commandline should read: <code>% {{kbd|1=ssh {{var|hostname}}}}</code> (where {{var|hostname}} is the IP address or domain name of the system to connect to); if this is correct, press {{key press|Enter}}."
* {{tnull|kbd|1{{=}}<nowiki>{{lorem}}</nowiki>|spacing{{=}}0}} to get rid of the spacing: {{kbd|1={{lorem}}|spacing=0}}

<!--The section below only makes sense if you remember that when /doc pages are included into the template page they belong to, their background is light green!
-->Some of these examples may look slightly different outside this documentation, because the default background color varies by page type (articles are stark white, template documentation pale green, most other pages very pale grey). In-article example:

<div style="background:#FFFFFF;">
* {{tnull|kbd|71077345}}: "Entering {{kbd|71077345}} on a calculator and turning it upside down appears to spell ''[[Royal Dutch Shell|ShellOil]]''."
* {{tnull|kbd|1{{=}}ssh <nowiki>{{var|hostname}}</nowiki>}} with {{tnull|samp|%}}: "At the {{samp|%}} prompt, the user must enter {{kbd|1=ssh {{var|hostname}}}}."
* {{tnull|kbd|1{{=}}ssh <nowiki>{{var|hostname}}</nowiki>}} with {{tnull|samp|%}} and {{tnull|key press|Enter}}: "At the {{samp|%}} prompt, the user must input {{kbd|1=ssh {{var|hostname}}}}{{key press|Enter}}."
* Inside {{tag|code}}: "The commandline should read: <code>% {{kbd|1=ssh {{var|hostname}}}}</code> (where {{var|hostname}} is the IP address or domain name of the system to connect to); if this is correct, press {{key press|Enter}}."
* {{tnull|kbd|1{{=}}<nowiki>{{lorem}}</nowiki>|spacing{{=}}0}} to get rid of the spacing: {{kbd|1={{lorem}}|spacing=0}}
