Where is the long dash on a French canadian keyboard?

Hi Buddy,

shift-option-0, as you found out.

Keyboard viewer is a useful tool for answering this type of question. It's found in the Input menu, which appears on the menu bar as the national flag associated with your chosen keyboard layout.

Show Input menu is a checkbox choice in System Preferences > Language and Region > Keyboard options:

The image shows the Canadian English KB Viewer superimposed on the Preferences pane the space behind the KB Viewer is empty). The checkbox in question is the one checked below the KB image,

Regards,

Barry

The longer dashes are at option shift 0 and option shift =.
