The "Title" text box at the top of the dialog contains the text that will display on mouse-over of the dock entry. You can change this text, or delete it. Deleting the text will result in no text being displayed on mouse-over. To change the text font and size, you can use the "ObjectDock Properties (AKA the "Dock Settings) > General category > Advanced Options" dialog, which is discussed in the "ObjectDock Plus – Create A Non-Tabbed Dock 101" mini tutorial.
2 – Assign a link for the new dock entry by using one of the following methods: (1) use the preset drop-down list, (2) use the Browse button to locate an "executable" file, or (3) type or paste the address to a folder or file in the "Link" text box. In this case, we will select "My Documents" from the preset drop-down list as shown in the image below:

Note - the "Arguments" text box is for command specific actions, and is beyond the scope of this mini tutorial.
3 – Select an image for your entry by clicking the "Change Image" button as shown in the image below:

This will invoke the Choose Image dialog, which is a basic explorer window allowing you to select a folder in the left pane, and then an image from the selected folder in the main pane as shown below:

Alternatively, you can use the "Browse" button to navigate to any ".ico" or ".png" file. Note – for editing and designing a theme which you intend to distribute, it is recommended that you keep all files in the ObjectDock sub-directory. This will make your theme more likely to be compatible with another users’ computer.
DRAG-N-DROP METHOD
On your keyboard, hold down the "Windows" key (key with flying window symbol), and immediately press the "E" key – to invoke "Explorer". Alternatively, you can open "My Computer" and click the "Folders" button in the toolbar. You can then drag-n-drop any icon from either the left pane, or main pane onto the dock – as illustrated by dragging the "My Computer" icon onto the dock - in the image below:

The result of dragging My Computer onto the dock is shown in the image below:

Note – change the text and image the same way indicated for the context menu method.
I have added a few other entries using the methods above to add some functional content to the dock, including the "Recycle Bin" – which I used the context menu method to illustrate it’s location in the menu as shown in the image below:

Make sure to change both the "Empty" and "Full" images for the recycle bin as shown in the image below:

DOCK BACKGROUND
Let’s polish the theme off with some increase in icon size, and a matching background for the dock, by right-clicking the dock and selecting "Dock Properties" as shown in the image below:

Click the "Appearance" category and use the "Icon Size" slider to increase icons to 72 pixels, and then use the "Background" drop-down list to select a background – as shown in the image below:

LOCKING FEATURE
You can lock the icons in place on the dock to prevent deleting one by accidentally dragging if off the dock and watching it disappear in a "POOF" – which I have managed to do a few times previous to the addition of this feature. To lock the icons in place, right-click the dock > select "Lock Dragging" as shown in the image below:

Well, that is all for this lesson.
I hope you found this mini tutorial useful. Until next time, have fun and "Keep On Customizing".
