Looking up the properties of the tag is the same as editing the tag to carry out modifications since it calls up the dialogue box used to create the command line.
Place your cursor at the beginning of the tag you want to look at.
Click the right mouse button to display the context menu.
Click Tag properties.
The dialogue box that corresponds to the tag being modified will appear. Modify the options.
You can also use the Alt+Enter keyboard shortcut (See the list of keyboard shortcuts).
