How do I add custom BBCode?

Hello, what I am trying to do is add custom BBCodes for staff members for example "announcement template" etc. Is there any place where I can do the BBCode or do I have to do a workaround? Add a button to the editor which when clicked insert the text in the editor?

Try:

Javascript:

Code: $(function() {   $.sceditor.command.set('newcmd', {     exec: function() {             this.insert('a');     },     txtExec: function() {             this.insert('a');     },     tooltip: 'Added new button'   });   if($.sceditor && window.toolbar) {      window.toolbar = window.toolbar.replace(/time,/gi, "time,newcmd,");   } });

CSS:

Code: .sceditor-button-newcmd {     background: url('/images/icon.png'); }
