"When in the symbol editor, and with nothing selected, press the O key for "Options", a menu will pop up with Document Options... at the top of the list. Click on Document Options... (the fast way is to press the O key and then the D key) You can also get there by the menu as Tools -> Document Options...
This will bring up the Library Options in the Properties panel. At the very bottom there is a check box for "Show Comment/Designator". Check this checkbox. The Comment string and the Designator string will now display in the symbol editor if they contain data in their values.
Now, in the symbol editor with the Comment and Designator displayed, you can select the Comment and/or the Designator string(s) and set the Autoposition, the Justification, Font and other settings in the Properties panel. You can also position them and they will keep that position, if they have Autoposition unchecked, when the symbol is placed in a schematic."
Thank you Thomas !
To remove the Position Dots
