Checkmark in code editor

Hi All
When I am in the editor I can right click and select checkmark. It will turn that line of code cyan background. I can do this for other lines of code. So these are what I call bookmarks. Can someone tell me how I can go from checkmark to checkmark. Their has got to be a hot key or menu option somewhere. Looked in help under checkmark. No help their. Thanks for any help.

Hi John,

with function key F7 you can go from checkmark to checkmark.

Hi
Thanks Stefan, I knew there had to be some kind of key. Also shift F7 will take you to the previous check mark.
