Im trying to add my own emoticon to skype but im having problems with a couple things. I've found the steps in order to add this but i need some help with accessing "emoticons.plist" with the property editor. Can someone tell me how to do this? The steps are listed below.

Step 1

Right click the Skype application and choose "Package Contents." Go to "Resources/Emoticons."

Step 2

Add your picture to the animated emoticon set folder or the emoticon set folder. In the animated folder you must save the file as a .gif, in the emoticon folder as .png.

Step 3

Open "emoticons.plist" with the property editor.

Step 4

Add an entry fpr for your smiley. Name the object as the file name with .gif in the animated folder and .png in the regular folder. Add the strings that you want to appear as the smiley and array the name equivalents. Create a boolena and name it hidden. If you have difficulty with the programming aspect you can check the entries of the other smileys for examples.

Step 5

Save and relaunch Skype.

How do you access "emoticons.plist" with the property editor.

Im using a Mac computer, furthermore, could you run me through this entire procedure step by step
