Thanks fir the reply, but it doesn't work completely.

I've tried it like

<li onclick="injectString( this.innerHTML);">½</li>

function injectString(str){
   var sel=frames[0].getSelection()
   var nd=sel.anchorNode;
   var txt=nd.data+'';
   var pos=sel.anchorOffset||0;
   sel.anchorNode.data=txt.slice(0,pos)+str+txt.slice(pos);
 }

Edit: It inserts ½ to the iframe, when there's something already typed there.

Looks like, it doesn't insert the symbol to the end of what originally typed. I need to either select some text or put the cursor in between two characters to get it work.

Edit: Also, it moves the cursor to the beginning of the typing area, after button click
