Examples, using {{Timc|x3}}<br />and {{Timc|t2}}:

*<ttkbd><nowiki>{{{a|b|c|d}}}</nowiki></ttkbd> gives <ttkbd>{{{A|b|c|d}}}</ttkbd>

*<ttkbd><nowiki>{{{a|{{x3|b}}}}}</nowiki></ttkbd> gives <ttkbd>{{{A|{{x3|b}}}}}</ttkbd>

*<ttkbd><nowiki>{{{a|{{{b|c}}}}}}</nowiki></ttkbd> gives <ttkbd>{{{A|{{{b|c}}}}}}</ttkbd>

*<ttkbd><nowiki>{{{a|[[b|c]]}}}</nowiki></ttkbd> gives <ttkbd>{{{A|[[b|c]]}}}</ttkbd>

*<ttkbd><nowiki>{{{{{x3|a}}|b}}}</nowiki></ttkbd> gives <ttkbd>{{{{{x3|a}}|b}}}</ttkbd> - parameter aaa is undefined

*<ttkbd><nowiki>{{{{{{a|b}}}|c}}}</nowiki></ttkbd> gives <ttkbd>{{{{{{A|b}}}|c}}}</ttkbd> - parameter b is undefined

*<ttkbd><nowiki>{{{a|<nowiki>b|c</nowiki><nowiki><</nowiki>/nowiki>}}}</ttkbd> gives <ttkbd>{{{A|<nowiki>b|c</nowiki>}}}</ttkbd> - works fine for rendering text, but is not suitable for putting parameters b and c in a template call (there is no function for removing nowiki tags):

*:<ttkbd><nowiki>{{t2|{{{a|<nowiki>b|c</nowiki><nowiki><</nowiki>/nowiki>}}}}}</ttkbd> gives <ttkbd>{{T2|{{{A|<nowiki>b|c</nowiki>}}}}}</ttkbd>
