There has been confusion about this Docker since Corel introduced Symbols in CorelDRAW 12. Many users still think of Symbols as the simple graphics contained in symbol fonts. To bring up the Docker, press Ctrl + F11. Not only will you see symbol fonts listed, but every single font available to CorelDRAW. Just yesterday I needed to insert the bullet character and couldn’t remember the keystroke for the character. I just brought up the Docker and dragged it into the block of text.
Some users don’t want to see all fonts. They just want the symbol fonts. Not a problem. Just right-click directly on the font name at the top of the Docker and you’ll get a pop-up menu showing which type of fonts are included. Uncheck the two “Fonts” choices and you’ll be left seeing only the symbol fonts.
